Abstract:Two new electronic transitions of TaF have been recorded at high resolution using Intracavity Laser Spectrscopy (ILS). The TaF molecules were produced in a current-regulated RF discharge operating with 0.35-0.40 A applied to a Ta-lined Cu hollow cathode. The hollow cathode was located within the resonator cavity of a dye laser, tunable over the 14,500-17,200 \wn range using DCM and R6G laser dyes. Effective pathlengths from 0.40-2.25 km were utilized with the ILS method. Five bands were observed with red-degraded bandheads near 15,366 \wn, 16,033 \wn, 15,630 \wn, 16,327 \wn, and 16,930 \wn that have been respectively assigned as the (0,0) and (0,1) bands of the [16.0] $\Omega$=0-\textit{X} $\Omega$=0 transition of TaF, and (0,1), (0,0), and (1,0) bands of the [16.3] $\Omega$=1-\textit{X} $\Omega$=0 transition of TaF. Rotational assignments for the transitions have been confirmed through combination difference analysis using the reported line positions of Ng \textit{et al.} [\textit{J. Chem. Phys.}, \textbf{146}, 094308 (2017)]. These line positions from Ng \textit{et al.} were included in the PGOPHER fit of the newly observed transitions. Results of the analysis will be presented.
