Raman tensors for AB₃C molecules

Abstract

Explicit expressions for the Raman tensor of AB,C molecules are reported in terms of the bond polariznbility parameters, By considering Fermi resonance between the v,, t v , and Zv, modes of CH,CI, CH,Br, CH,I and CH,F molecules, the relatiomhips between the mean values of the polarizability derivatives with respect to dimensionless normal coordinates of these modes bave been found.
