Abstract
The rotationally resolved laser induced fluorescence spectra for the ${^{1}}A^{\prime} - \widetilde{X} {^{1}}\Sigma^{+}$ electronic transition of AlNC and AlCN were measured in supersonic free expansions. The radicals were prepared by reacting the CN fragments from $CH_{3}CN$ in an Ar plasma with Al atoms evaporated using laser ablation of the metal surface. The electronic spectrum of AlCN was observed at about $2500 cm^{-1}$ above that of AlNC reported $previously^{a}$, and the fluorescence state is much lower than that reported by Gerasimov $et al^{b}$. The rotational structures of both AlNC and AlCN spectra measured by a excitation laser source with $0.03 cm^{-1}$ spectral resolution show a typical pattern of bent-linear transition.
