WebTranscribed Image Text: QUESTION 1 Which of the following statements related to the Franck-Condon principle are true? (Select all that apply.) The nuclei move at about the same speed as the electrons and change position as the molecule is electronically excited. The nuclei can be considered stationary during an electronic transition. Webthe Franck-Condon integral. If the vibrational wavefunction of either the lower or upper electronic state is non-totally symmetric, the Franck-Condon integrand will be non-totally …
