Abstract

Substantial changes of population lifetimes of CH-stretching modes are observed when two atoms are exchanged in CH2=CCl2 to form trans CHCl=CHCl and when three deuterons are substituted in C6H6 to form 1,3,5.-C6H3D3. The measured lifetimes are in good agreement with estimates based on Fermi resonance-mixing which is inferred from infrared and Raman spectra.
