Abstract

The (2,0) vibrational band of the A 2Σ- - X 2Π1/2 transition of platinum nitride, PtN, was recorded at Doppler-limited resolution using intracavity laser absorption spectroscopy (ILS) and at sub-Doppler resolution using molecular beam laser induced fluorescence (LIF) spectroscopy. Isotopologue structure for 194PtN, 195PtN, and 196PtN, magnetic hyperfine splitting due to 195Pt (I =F), and nuclear quadrupole splitting due to 14N (I = 1) were observed in the spectrum. Molecular constants for the ground and excited states are derived. The hyperfine interactions are used to illuminate the nature of the A 2Σ- excited electronic state.
