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)A′ 1Π→X 1Σ+ (T 00=13 196.13 cm-1) and (0,0)A 1Σ + (T00=18 510.71 cm-1) band systems of PtC were recorded at a resolution of ∼0.001 cm -1. The magnetic hyperfine splitting exhibited in the spectral features of the 195PtC isotopomer was analyzed and indicates that the A′ 1Π and A 1Π states arise primarily from a... σ1π1; and a...δ3π1 configurations, respectively.
