✦ Synopsis

High-resolution emission spectra of TiCl have been recorded in the 10 000 -18 000 cm Ϫ1 region using a Fourier transform spectrometer. The molecules were excited in a microwave discharge through a flowing mixture of TiCl 4 and helium. TiCl bands observed in the 11 000 -13 500 cm Ϫ1 region have been assigned to a new [12.8] 2 ⌽-a 2 ⌽ electronic transition with the 0 -0 bands of 2 ⌽ 5/2 -2 ⌽ 5/2 and 2 ⌽ 7/2 -2 ⌽ 7/2 subbands at 12 733.7 and 12 791.5 cm Ϫ1 , 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.

The emission spectrum of ZrCl has been observed in the 1800 -12 000 cm Ϫ1 region using a Fourier transform spectrometer. The molecules were excited in a microwave discharge of a mixture of helium and a trace of ZrCl 4 vapor. In addition to the C 4 ⌬-X 4 ⌽ transition reported previously, numerous new
