Abstract

We report a theoretical study on the valence-shell electronic excitations of N2O induced by electron impact. Momentum transfer-dependent generalized oscillator strengths (GOSs) or GOS profiles have been calculated for the low-lying electronic excitations using theoretical wave functions at the equation-of-motion coupled-cluster singles and doubles level. In the calculation, Herzberg-Teller vibronic effects are taken into account. The computed results are in overall agreement with experimental GOS profiles reported in the literature and reveal prominent roles of the bending vibration of N2O in the B1Δ and C1Π transitions.
