Abstract

A new electronic transition of PtF has been recorded at high resolution using Intracavity Laser Spectroscopy (ILS). The PtF molecules were produced in a current regulated RF discharge operating with 0.20-0.80 A applied to a Pt-lined Cu hollow cathode in 0.50-1.25 Torr total pressure comprised of 1-5\% SF$_{6}$ in an Ar/He sputter gas mixture. This hollow cathode was located within the resonator cavity of a tunable DCM dye laser operating over the 14,500-16,500 \wn $ $ range, and effective pathlengths of 0.4-2.0 km were utilized with the ILS method. The band system observed corresponds to the (0,0) band of the [15.3]$\Omega$=3/2 – \textit{X} $^{2}$$\Pi$$_{3/2}$ transition. Rotational assignments for the transitions have been confirmed through combination difference analysis using known ground state constants. The data were fit using PGOPHER with a standard Hund’s case (\textit{c}) energy level expression. Spectra and results of the analysis will be presented.
