Abstract
The spectra of TiCl have been reinvestigated in the 4200-8500 cm(-1) region using the 1-m Fourier transform spectrometer associated with the National Solar Observatory at Kitt Peak. The molecules were excited in a microwave discharge lamp operated with 3.0 Torr of He and a trace of TiCl4 vapor, and the spectra were recorded at a resolution of 0.01 cm(-1). Three new bands with origins near 6938.9, 6900.2. and 6861.7 cm(-1) have been assigned as the 0-0, 1-1, and 2-2 bands of a new (2)Sigma-(2)Sigma transition. This assignment is supported by our recent ab initio calculations on TiCl and ZrCl [J. Chem. Phys. 114 (2001) 3977]. A rotational analysis of these bands has been carried Out and spectroscopic constants have been extracted for the (2)Sigma states. (C) 2004 Elsevier Inc. All rights reserved.
