Electronic excitation can result in much larger changes in bond length than vibrational excitation, and the rotational branches have a more complex struct If the vibrational quantum number (n) changes by one unit, then the rotational quantum number (l). During an electronic transition, a change from one vibrational energy level to another will be more likely to take place if the two vibrational wave functions overlap more significantly.

We begin by labelling molecular orbitals according to their symmetry and assigning term symbol to ground and.
Electronic transition refers to the movement of an electron from one energy level to another within an atom or molecule.
17.1 the electronic spectra of diatomic molecules by using diatomic molecules as examples. These transitions are categorized primarily into electronic, vibrational, and rotational transitions, each offering unique insights into different aspects of molecular behavior. On the other hand, vibrational transitions. It explains that energy levels come.
The image below shows a summary that connects the specific regions of the electromagnetic spectrum and the types of molecular and electronic transitions associated with them The combined excitation is known as a vibronic transition, giving vibrational fine structure to. Seen for each vibrational transition. Three types of energy levels in a diatomic molecule:
This process is a fundamental aspect of the interactions between light and matter.
