Abstract

The chloromethylene radical, HCCl, was first observed in the gas phase by Merer and Travis1. They found that the molecule in the excited state is ``straightened” by vibration and that the (010) level is below the barrier to linearity. The (010)-(000) band around 13150cm−1 has been observed with Doppler - limited resolution of 0.03cm−1 using a CW dye laser. The HCCl molecule was generated by a reaction of discharged CF4 with CH3Cl. A rotational analysis will be presented.
