Author Institution:Fluorescence spectra of the near vaccum ultraviolet A~1A′′→X~1Σ+ transition of HCN have been recorded and assigned. A tuned (0.15A bandwidth) ArF excimer lasser is used to excite the (010)1, (000)2 and (000)0 individual vibronic features in the A~1A′′ state. Fluorescence terminating on high vibrational levels of the X~1Σ+ state dominates the emission spectra. Progressions in the v2​ bending and v3​ stretching modes are assigned. The fluorescence spectra, emission assignments, fluorescence lifetimes and the fluorescence excitation spectrum will be reported and discussed
