✦ Synopsis

Emission spectra of the O-O bands of the transitions X, *II ,,z+X, 2lI3,1 between the fine-structure components of the X'rI, ground states of TeF, TeCl, TeBr and TeI have been observed in the near-infrared spectral region between 2.35 and 2.5 pm. The X22n,,2 states of the radicals were excited by addition of halogens to the reaction system of microwavedischarged H2 with tellurium powder in a fast-flow system. The fine-structure splittings of the X 'Hi ground states were found to be 4187k 1 cm-' (TeF), 4022Srf I cm-' (TeCl), 4067k 3 cm-' (TeBr) and 41304 10 cm-' (TeI).
