LASER INDUCED FLUORESCENCE OF HCN FROM THE $\tilde{A} {^{1}}A''$ STATE
Publisher:
Ohio State UniversityAbstract:
Fluorescence spectra of the near vaccum ultraviolet $\tilde{A} ^{1} A^{\prime\prime} \rightarrow \tilde{X} ^{1}\Sigma^{+}$ 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 $\tilde{A} ^{1} A^{\prime\prime}$ state. Fluorescence terminating on high vibrational levels of the $\tilde{X}^{1}\Sigma^{+}$ state dominates the emission spectra. Progressions in the $v_{2}$ bending and $v_{3}$ stretching modes are assigned. The fluorescence spectra, emission assignments, fluorescence lifetimes and the fluorescence excitation spectrum will be reported and discussed.
