摘要：

A rotational analysis of the electronic transition of PtF occurring at 15,252 cm(-1) was recorded and analyzed. This transition is identified as the (0,0) band of the [1.5.3]Omega=3/2 - X-2 Pi(3/2) electronic transition. The PtF molecules were produced in a current regulated RF-pulsed DC discharge operating with 0.80 A applied to a Pt-lined copper hollow cathode in 0.50-1.25 Torr of 1-5% SF6 in an Ar/He sputter gas mixture. The hollow cathode was placed within in the resonator cavity of a tunable DCM dye laser operating over the 14,500-16,500 cm(-1) range, and path lengths of 0.2-2.0 km were utilized with the intracavity laser spectroscopy (ILS) method. The data were fit in PGOPHER using a polynomial energy level expression. Molecular constants for the excited state are presented. The nature of the new [15.3]Omega = 3/2 state is discussed.
