摘要: Platinum nitride, PtN, was identified in the supersonic coexpansion of a laser ablation generated platinum vapor and ammonia by induced fluorescence spectroscopy. The intense blue band system assigned as (0,0) d 4Π1/2–X 2Π1/2 transition with determined spectroscopic fine parameters being (in cm−1):T00=18586.3608(28), B‘=0.4541(7), (p+2q)‘=0.1219(15), B’=0.4164(7), (p+2q)’=0.2039(8). Stark shifts splitting were analyzed to produce ground excited electronic state values for permanent electric dipole moment 1.977(7)D 1.0(1)D, respectively. field free spectrum 195Pt isotopomer magnetic hyperfine cm−1) h1/2‘= 0.0639(30), h1/2’ = 0.1571(36), d’=−0.0979(7), d‘=−0.0034(15). A sophisticated ab initio calculation physical properties low‐lying states performed. experimental results are generally consistent predictions that is d 4Π1/2–X...
