چکیده انگلیسی
The vibration-rotation emission spectra for the X2Î ground state and the near infrared emission spectra of the X2Î 1/2-X2Î 3/2 system of the TeH and TeD free radicals have been measured at high resolution using a Fourier transform spectrometer. TeH and TeD were generated in a tube furnace with a DC discharge of a flowing mixture of argon, hydrogen (or deuterium), and tellurium vapor. In the infrared region, for the X2Î 3/2 spin component we observed the 1-0, 2-1, and 3-2 vibrational bands for most of the eight isotopologues of TeH and the 1-0 and 2-1 bands for three isotopologues of TeD. For the X2Î 1/2-X2Î 3/2 transition, we observed the 0-0 and 1-1 bands for TeH and the 0-0, 1-1, and 2-2 bands for TeD. Except for a few lines, the tellurium isotopic shift was not resolved for the X2Î 1/2-X2Î 3/2 transitions of TeH and TeD. Local perturbations with Îv = 2 between the two spin components of the X2Î state of TeH were found: X2Î 1/2, v = 0 with X2Î 3/2, v = 2; X2Î 1/2, v = 1 with X2Î 3/2, v = 3. The new data were combined with the previous data from the literature and two kinds of fits (Hund's case (a) and Hund's case (c)) were carried out for each of the 10 observed isotopologues: 130TeD, 128TeD, 126TeD, 130TeH, 128TeH, 126TeH, 125TeH, 124TeH, 123TeH, and 122TeH.
