Abstract
High-resolution emission spectra of TiCl have been recorded in the 10 000-18 000 cm(-1) region using a Fourier transform spectrometer. The molecules were excited in a microwave discharge through a flowing mixture of TiCl4 and helium. TiCl bands observed in the 11 000-13 500 cm(-1) region have been assigned to a new [12.8](2)Phi-a(2)Phi electronic transition with the 0-0 bands of (2)Phi(5/2)-(2)Phi(5/2) and (2)Phi(7/2)-(2)Phi(7/2) subbands at 12 733.7 and 12 791.5 cm(-1), respectively. A rotational analysis of several bands has been obtained, and spectroscopic constants have been extracted. This assignment is supported by the available theoretical calculations and is also consistent with the near infrared measurements of a doublet- doublet transition of ZrCl [J. G. Phillips, S. P. Davis, and D. C. Galehouse, Astrophys. J. Suppl. Ser. 43, 417-434) (1980)]. (C) 1999 Academic Press.
