Abstract The gaseous products generated in the supersonic coexpansion of laser ablated platinum vapor with methane or acetylene were probed by visible laser induced fluorescence (LIF) spectroscopy. Both platinum monocarbide, PtC, and an unidentified Pt-containing polyatomic molecule were detected. The intense (0,0){ital A}{prime} {sup 1}{Pi}{r_arrow}{ital X} {sup 1}{Sigma}{sup +} ({ital T}{sub 00}=13 196.13 cm{sup {minus}1}) and (0,0){ital A} {sup 1}{Pi}{r_arrow}{ital X} {sup 1}{Sigma}{sup +} ({ital T}{sub 00}=18 510.71 cm{sup {minus}1}) band systems of PtC were recorded at a resolution of {similar_to}0.001 cm{sup {minus}1}. The magnetic hyperfine splitting exhibited in the spectral features of the {sup 195}PtC isotopomer was analyzed and indicates that the {ital A}{prime} {sup 1}{Pi} and {ital A} {sup 1}{Pi} states arise primarily from a...{sigma}{sup 1}{pi}{sup 1} and a...{delta}{sup 3}{pi}{sup 1} configurations, respectively.
