The effect of the noncorrespondence of normal coordinates on the Franck-Condon factors governing the appearance of non-totally symmetric vibrations in electronic spectra is examined. In a two-dimensional symmetry species containing vibrations 1 and 2, transitions such as 1 1 0 2 1 0 , 1 1 0 2 3 0 ,
The effect of strong Duschinsky type mixing of two normal coordinates Q1 and Q2 on the intensity of transitions in non-totally symmetric vibrations in electronic spectra is examined. Using a Fermi resonance type theory, expressions are derived for the intensity of transitions such as 1(1)02(0)1 and
