Abstract
A theory for vibronic excitation by electron impact is formulated from the viewpoint of the frame transformation theory. Simple expressions are obtained for resonant excitation of rotational state-to-state vibronic cross sections in Raman modes. For infra-red modes, the dipole interaction is accounted for coherently with the resonance mechanism. Explicit results are given in CO2 and C2H2.Keywords
