The gas-phase hser-induced fh~orcscence -excitation spectrum of dichlorocarbene (CC%) has been observed in the 498-534 nm spectral region. Suftick;; resolution has been obtained to partially resolve the band structure arising from the symmetrical stretching and bending vibrations. which leads to vib

The vIbrational structure in the laser-induced fluorescence excitation spectrum of the fust excited TT\* .-n transition of thiophogene, seeded in a supersonic beam of argon, is reported. Hot bands are identified empirically by variation of beam temperature, and vibronic assignments are adjusted as r
Fluorescence has been observed from the second excited singkt stste of tkiophosgene vapour. The emission is excited mainly by transitions originating in the out-of-plane bending mode of the ground stzte and terminating in the lowest vibrational levekof the-excited state. i '.
A high-resolution laser excitation spectrum of the 0: band of OcS+ (A zIII, c, w 2II,) has been obtained in a dscbarge flow apparatus. Rotational analysis yields the constants (cm-') of \*aO\*2C32St: voo = 31404.099(7), BA(;) = 0.18718(13), B;(s) = 0.19477(9).
The dynamic behavior of the second excited singlet state of QCS has been investigated for the first time in liquid solutions. In perfluoroalkane solvents strong B-ji. fluorescence (@f up to 0.077) 1s observed when the molecule is excited to bound vibrational states. s lifetimes of up 10 2.8 ns are o
