| Unlike light Group 6A hydrides, the electrons in H2Te are relativistic and the molecule is highly unstable: hydrogen telluride gas decomposes upon slightest provocation and tellurium deposit is an obvious product. A detailed account of different synthesis methods and a thorough presentation of the experimental details of synthesizing hydrogen telluride gas using zinc telluride as a precursor are discussed. Problems encountered applying the current method are addressed and plausible solutions are presented.; The ultraviolet absorption spectrum of H2Te revealed a fascinating long wavelength tail that extends ∼400 nm. Employing the High-n Rydberg Time-of-Flight technique, photodissociation of hydrogen telluride at 266 nm and 355 nm wavelengths yielded rovibrationally state-resolved translational energy of H-atom product channels, both the primary and secondary photolysis of H2Te. The spectra showed a clear anisotropy of the two spin states of the primary photolysis. The calculated D0(H-TeH) was 22,700 +/- 100 cm-1. |
