The Frank-Condon Principle states that transitions between electronic states correspond to vertical lines on an energy vs. internuclear distance diagram. The basis of this principle is that electronic transitions happen on a timescale that is significantly smaller than the vibrational period of a given molecule and therefore the distance at which they happen can be assumed to be fixed during the transition. This is significant for spectroscopy because the most intense spectral lines will correspond to transitions to the vibrational state in the upper electronic state that have the most overlap with the ground vibrational state in the lower electronic state. (From Thomas Engel's Quantum Chemistry and Spectroscopy)
The Franck-Condon principle states that during an electronic transition, the nuclei of a molecule remain stationary. This principle allows for the approximation of the vibrational modes of the molecule before and after electronic excitation. It is particularly important in understanding processes such as absorption and emission spectra in spectroscopy.

WHAT FRANK-condon principle says with respect to spectroscopy?
The Franck-Condon principle states that in a molecular electronic transition, the nuclei of the molecules will remain in the same vibrational state before and after the transition. This principle is important in spectroscopy as it explains the intensity and shape of spectral lines. It allows for the determination of relative energies of electronic states and can provide insight into molecular structure and bonding.

What if there is a Frank Sr. then a Frank Jr. then a son of Frank Jr. what is the son referrred to as?
Frank Jr. becomes Frank Sr. and the Frank formerly known as Frank Jr.'s son becomes Frank Jr. ... If that makes any sense. Alternatively if Frank Sr. was the first Frank ie Frank the first, then the answer is Frank III ie Frank the third. Same as Queen Elizabeth II.
