Abstract
The (0,0) and (1,0) vibrational bands of the A Ω = 1 – X 3Σ‒0+ transition of PtS have been observed in high resolution absorption measurements recorded using intracavity laser spectroscopy with Fourier transform detection (ILS-FTS). Hyperfine structure in 195PtS lines was observed in the Q-branches only, due to the interaction of an unknown Ω = 0‒ state with the f levels of the A Ω = 1 state. The new (0,0) vibrational band has been rotationally analyzed and fit using PGOPHER. Results from the spectral analysis including deperturbation of the (0,0) band of the A Ω = 1 state are presented. Potential energy curves, spectroscopic constants, and transition dipole moments are presented for Λ-S and Ω electronic states with Te < 25,000 cm−1, based on high-level ab initio calculations. Experimentally observed electronic states of PtS are correlated to predicted states.
