title: Optical Stark spectroscopy of the 2(0)(6) Ã1A''-X̃1A' band of chloro-methylene, HCCl.
abstract: The laser induced fluorescence spectra of the 2(0)(6)Ã(1)A('')-X̃(1)A(') 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 Ã(1)A('') (060) vibronic state. The magnitude of the a-component of the permanent electric dipole moment, μ(a), for the X̃(1)A(') (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.
