FLUORESCENCE-SPECTRUM OF HCN (A1A''-]X1-SIGMA+) USING ARF LASER EXCITATION

The fluorescence spectrum of HCN A≈(1A′') → X≈(1Σ+) is reported using a tuned ArF laser as the excitation source. Assignments for the fluorescence spectra from two upper state vibrational levels are given. Franck-Condon factors for the absorption and fluorescence spectra are calculated. A laser-induced fluorescence spectrum is given which agrees with published absorption spectra of HCN. © 1979.
