Electronic states of diatomic molecules

Diatomic molecules, composed of two atoms, possess electronic configurations that are analogous to those found in atoms. However, the presence of two nuclei introduces complexities, leading to molecular orbitals that are distinct from atomic orbitals. These molecular orbitals are formed by the linear combination of atomic orbitals (LCAO). The electronic states of a diatomic molecule describe the distribution of electrons among these molecular orbitals and the overall electronic energy of the molecule.

When atoms combine to form a diatomic molecule, their atomic orbitals overlap and merge to form molecular orbitals. These molecular orbitals can be classified as either bonding or antibonding. Bonding orbitals are lower in energy than the original atomic orbitals and contribute to the stability of the molecule by increasing electron density between the nuclei. Antibonding orbitals are higher in energy and destabilize the molecule by decreasing electron density between the nuclei.

The electronic configuration of a diatomic molecule is determined by filling these molecular orbitals with the available valence electrons, following the Aufbau principle, Pauli exclusion principle, and Hund's rule. The ground electronic state is the lowest energy state, while excited electronic states correspond to higher energy configurations where one or more electrons are promoted to higher energy molecular orbitals.

Each electronic state is characterized by its electronic energy, internuclear distance, and symmetry properties. The electronic energy is a function of the internuclear distance, and plotting this energy against internuclear distance gives rise to potential energy curves. For a given electronic state, the potential energy curve typically resembles that of a harmonic oscillator or an anharmonic oscillator, with a minimum at the equilibrium internuclear distance.

The electronic state is often denoted by a symbol that includes a Greek letter representing the projection of the total electronic orbital angular momentum onto the internuclear axis, and a superscript indicating the total spin multiplicity. For example, a ¹Σ state signifies a state where the projection of the orbital angular momentum is zero (Σ) and the spin multiplicity is one (singlet state, 2S+1 = 2(0)+1 = 1). A ³Π state indicates a projection of orbital angular momentum of ±1 (Π) and a spin multiplicity of three (triplet state, 2S+1 = 2(1/2)+1 = 3).

The transition between different electronic states, often accompanied by changes in vibrational and rotational states, gives rise to electronic spectra. These spectra provide invaluable information about the electronic structure and bonding in molecules.

Franck–Condon principle

The Franck–Condon principle is a fundamental concept in spectroscopy that explains the intensities of vibronic transitions, which are transitions involving simultaneous changes in electronic and vibrational energy levels. It states that electronic transitions occur much faster than nuclear motion. This means that during an electronic transition, the nuclei of the molecule remain in approximately the same position and with approximately the same momentum.

Consider a diatomic molecule in its ground electronic state with a particular vibrational level. When the molecule absorbs a photon and transitions to an excited electronic state, the electronic configuration changes instantaneously. Since the nuclei cannot move during this rapid transition, the molecule finds itself in the excited electronic state but at the same internuclear distance as it was in the ground state.

The probability of a particular vibronic transition is proportional to the square of the overlap integral between the vibrational wavefunctions of the initial and final electronic states. Mathematically, the intensity of a transition from vibrational state $v'$ in the ground electronic state to vibrational state $v''$ in the excited electronic state is proportional to $| \langle \psi_{v''} | \psi_{v'} \rangle |^2$. This integral is known as the Franck–Condon factor.

If the potential energy curves of the ground and excited electronic states are similar in shape and their equilibrium internuclear distances are nearly the same, then the vibrational wavefunctions for corresponding vibrational quantum numbers will overlap significantly. In this case, the transition with no change in vibrational quantum number ($v' = v''$) will be the most intense.

However, if the equilibrium internuclear distance changes significantly upon electronic excitation, or if the shapes of the potential energy curves differ, the overlap between vibrational wavefunctions will be less. In such cases, transitions to different vibrational levels in the excited state will have significant intensities. For instance, if the excited state has a larger equilibrium internuclear distance, the most intense transition will be from the ground vibrational level ($v'=0$) of the ground state to a higher vibrational level ($v''>0$) of the excited state, corresponding to the overlap of the vibrational wavefunctions at the turning points of the classical motion in the ground state.

The Franck–Condon principle helps to interpret the complex patterns of spectral lines observed in electronic absorption and emission spectra. It explains why some vibronic transitions are strong while others are weak, based on the geometry changes between the electronic states.

Hund's coupling schemes

Hund's coupling schemes are empirical rules that describe the ordering of energy levels in diatomic molecules arising from the coupling of different angular momenta. These schemes are crucial for understanding the fine structure of molecular electronic states, particularly for states with orbital and spin angular momentum. There are four main Hund's coupling cases, denoted as (a), (b), (c), and (d), which apply under different conditions of molecular field strength and spin-orbit coupling.

Hund's Case (a)

In Hund's case (a), the electrostatic interaction between the electrons and the attraction of the electrons to the molecular axis are strong. The orbital angular momentum of each electron, $l_i$, couples with its spin angular momentum, $s_i$, to form a total electronic angular momentum for each electron, $j_i$. These $j_i$ vectors then couple together to form a total electronic orbital angular momentum $\mathbf{L}$ and a total electronic spin angular momentum $\mathbf{S}$. The strong interaction with the internuclear axis causes the projection of $\mathbf{L}$ onto the internuclear axis, denoted by $\Lambda$, to be well-defined. Similarly, the projection of $\mathbf{S}$ onto the internuclear axis, denoted by $\Sigma$, is also well-defined. The total electronic angular momentum projected onto the internuclear axis is $\mathbf{\Omega} = \mathbf{\Lambda} + \mathbf{\Sigma}$. The quantum number $\Omega$ takes values from $|\Lambda - S|$ to $\Lambda + S$ in integer steps. The molecular electronic state is designated as $^ {2S+1}\Lambda_\Omega$. This case is usually valid for lighter diatomic molecules in states where $\Lambda$ is not zero.

Hund's Case (b)

In Hund's case (b), the interaction of the electronic orbital angular momentum with the internuclear axis is weak, but the interaction of the electron spins with each other is significant. Here, $\mathbf{L}$ and $\mathbf{S}$ are coupled to form a total electronic angular momentum $\mathbf{J}_{el}$. However, the coupling of the orbital angular momentum of the electrons to the internuclear axis is weak, so $\Lambda$ is not well-defined. Instead, the resultant orbital angular momentum $\mathbf{L}$ couples with the resultant spin angular momentum $\mathbf{S}$ to form a total angular momentum $\mathbf{J}_{el}$. The projection of this resultant orbital angular momentum onto the internuclear axis is not the primary coupling. Instead, the total electronic spin $\mathbf{S}$ couples with the molecular axis to give $\Sigma$. The projection of the total electronic orbital angular momentum onto the internuclear axis, $\Lambda$, is not a good quantum number in this case. Instead, $\mathbf{L}$ and $\mathbf{S}$ couple to form a resultant $\mathbf{J}_{el}$. The interaction of $\mathbf{L}$ with the axis is weak. The resultant $\mathbf{L}$ couples with $\mathbf{S}$ to form a resultant $\mathbf{J}_{el}$. The interaction with the axis is not strong enough to define $\Lambda$. Instead, $\mathbf{L}$ and $\mathbf{S}$ couple to form $\mathbf{J}_{el}$. The interaction of $\mathbf{L}$ with the internuclear axis is weak. The resultant orbital angular momentum $\mathbf{L}$ couples with the resultant spin angular momentum $\mathbf{S}$ to form a total angular momentum $\mathbf{J}_{el}$. However, the projection of $\mathbf{L}$ onto the internuclear axis is not well-defined. Instead, the individual electron orbital angular momenta couple to form $\mathbf{L}$, and the individual electron spin angular momenta couple to form $\mathbf{S}$. The overall electronic state is characterized by $\Lambda$ and $S$. The total electronic angular momentum $\mathbf{J}_{el}$ is formed by coupling $\mathbf{L}$ and $\mathbf{S}$. The molecular axis plays a role in coupling $\mathbf{L}$ and $\mathbf{S}$ to form $\mathbf{J}_{el}$.
