Electronic spectroscopy has been used to study two metal nitrides: platinum nitride and zirconium nitride. The (2,0) band of the A 2Σ- – X2Π 1/2 electronic transition of PtN has been recorded at high resolution using intracavity laser absorption spectroscopy. The gas-phase PtN molecules were produced in a platinum-lined hollow cathode sputter source at low pressure. Isotopologue structure for 194PtN, 195PtN and 196PtN was observed in the spectrum, as was splitting due to the 195PtN nucleus (I=1/2). The (0,0) band of the A 2Π3/2 – X2Σ + transition of ZrN is known to be perturbed. The perturbing states are determined to be three 2Δ states. ZrN was produced in a hollow cathode sputter source, and the spectrum was recorded in emission by a high resolution FT spectrometer. Both PtN and ZrN were analyzed using PGOPHER, and molecular parameters and a full analysis are presented.
