Electronic spectra of OThF have been recorded within the 21740 -29410 cm -1 range using fluorescence excitation, dispersed fluorescence, and two-color photoionization techniques. Jet expansion cooling was used to reduce the rotational temperature of the OThF to approximately 30 K. The spectrum exhibited well-defined vibronic bands. Rotational resolution was not achieved, but partially resolved rotational contours were examined for the more intense features.
