The (2,0) band of the A^{2 -} - X² _1/2 electronic transition of PtN has been recorded using intracavity laser absorption spectroscopy. Transitions from ¹⁹⁴PtN, ¹⁹⁵PtN, and ¹⁹⁶PtN isotopologues are observed, as well as the nuclear hyperfine splitting due to ¹⁹⁵Pt with I=1/2. The results of the analysis will be presented and compared with ab initio calculations.
