The observation of the C-Cl stretching fundamental of HC35Cl in its ground X̃ 1A′' state is reported. HCCl was formed in a continuous flow system by the excimer laser photolysis of CHBr2Cl at 193 nm and the transient absorption recorded by infrared diode laser spectroscopy. The band has a-type character and the fundamental vibrational frequency is found to be 811.5963 cm-1. No evidence was found for perturbations in either the ground or vibrationally excited states, implying that the excited triplet ̃3A″ states lies above the C-Cl stretching level in HCCl. The observed rotation-vibration transitions were well fit by a standard asymmetric rotor Hamiltonian. There is a decrease in the A rotational constant on vibrational excitation, suggesting that some bend-C-Cl stretch coupling is present.
