The infra-red spectrum of C₂HD around 700 cm^-1

Abstract

The absorption spectrum of C₂HD in the region of the bending fundamental v ₅ has been studied. In addition to the fundamental, all the hot bands starting from the vibrational levels v ₄ and v ₅ have been investigated. Several molecular parameters have been derived. Special attention has been paid to the effects of l-type resonances on the vibrational levels 2v ₅ and v ₄ + v ₅.
