摘要

En 中文
A high-resolution spectrum of hydrogen telluride (H2Te) was recorded in the 4050-7000 cm(-1) region. Two bands could be observed at 4900 and 5980 cm(-1) and were assigned as the (20(+/-),1)<-(00(+),0) and (30(+/-),0)<-(00(+),0) bands, respectively. Rotational transitions of the two bands were assigned for the most abundant (H2Te)-Te-130 and (H2Te)-Te-128 isotopic species. Line position analyses were carried out to investigate a possible local mode behavior. For the first time we found in H2Te strong experimental evidence for such a behavior for the higher-lying band as its two upper vibrational states are only 0.027 and 0.032 cm(-1) apart for the (H2Te)-Te-130 and (H2Te)-Te-128 isotopic species, respectively.
