Question

describe franck codon principle​

Answer 1

Answer:

According to the Franck–Condon principle, the intensity of a vibrational peak in an electronically allowed transition is proportional to the absolute square of the overlap integral of the vibrational wave functions of the initial and final states. This overlap integral is known as the Franck–Condon factor.

Answer 2

Answer:

The Franck–Condon principle is a statement on allowed vibrational transitions between two different electronic states; other quantum mechanical selection rules may lower the probability of a transition or prohibit it altogether.
