Abstract

A new cavity rindgdown spectrometer has recently been assembled within the Arkansas Center for Laser Applications and Science (ArCLAS). In order to evaluate this new spectrometer, high resolution rovibrational and rovibronic spectra have been collected for a number of molecular species including oxygen and acetylene. These spectra have been analyzed and compared with corresponding data from the literature. During the instrumental evaluation process several overtone/combination bands of 13C₂H₂ were recorded in the 13,200-13,500 cm-1 region that currently appear to be missing from the literature. Forty-three lines have been assigned for the (tentatively assigned) 2ν₂ + 3ν₃ band, while forty-two have been assigned for a second Π←Σ band. These rovibrational assignments have been used to determine a set of excited state rotational constants for both bands. This data will be useful in extending the 13C₂H₂ theoretical predictions into the 13,000 cm-1 region.
