Abstract

The rotationally resolved spectrum of the HCCl ̄A¹A' implied by ̄X¹A' transition at near infrared (IR) wavelengths was obtained at Doppler-limited resolution using a combination of transient absorption and frequency modulation (FM) techniques. The analysis of the observed spectrum reveals perturbations arising from both the Renner-Teller effect and the singlet-triplet interaction between these states and the low-lying ̄a³A' state as well as information concerning the geometry and the vibrational structure in the excited singlet state.
