Question

According to Franck-Condon’s principle, which of the following transitions will give intense band ?
(i) V = 0 to V = 4
(ii) V = 1 to V = 4
(iii) V = 0 to V = 2
(iv) V = 0 to V = 3​

Answer 1

Answer:

i think the option c is the correct one

Answer 2

The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy.
