A. State Frank-Condon principal
B. State Born- Oppenheimer approximation
Franck Cordon principle:
The F-C principle states that the electron's transition occur so rapid that the nuclei can be taken as a stationary unit until the transitions are complete.
In simple words, It is an approximation that the electron's transition is mainly likely to occur without any change in position of nuclei in molecular structure and its environment.
