Abstract

The (2,0) vibrational band of the A ²Σ^- - X ²Π_1/2 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.
