The laser induced fluorescence spectra of the 2 0 6 ∼A 1A″-X 1A′ band of a rotationally cold (<20 K) molecular beam sample of chloro-methylene, HCCl, has been recorded, field-free and in the presence of a static electric field. The field-free spectrum has been analyzed to produce an improved set of spectroscopic parameters for the ∼A 1A″ (060) vibronic state. The magnitude of the a-component of the permanent electric dipole moment, a, for the X 1A′ (000) vibronic state has been determined to be 0.501(1) D from the analysis of the observed electric field induced shifts. Comparisons with theoretical predictions and flouro-methylene, HCF, are presented.
