Abstract
The emission spectrum of TaCl has been recorded at high resolution in the 3000-35 000 cmâ1 region using a Fourier transform spectrometer. The bands were observed by microwave excitation of a mixture of TaCl5 vapor and 3.0 Torr of He. Several TaCl bands have also been recorded using the laser ablation/molecular beam source at the University of New Brunswick. A rotational analysis of a number of bands has been obtained and the majority of the stronger bands have been classified into three groups with different lower state spectroscopic constants. The three lower states have been identified as having Ωâ³Â = 0+, Ωâ³Â = 2, and (tentatively) Ωâ³Â = 3. The Ωâ³Â = 0+ and Ωâ³Â = 2 states are very close in energy and one of these two states is the ground state of TaCl.
