Abstract

In the first part of this paper, an analysis of the high-resolution spectrum of the HTO molecule ν₁(ν₃) band, from 3630 to3950 cm^–1, was undertaken. The rotational transition of this band was assigned using combination differences. Their wavenumbers were analyzed with a least squares fit program in order to obtain spectroscopic constants. A perturbed state has been evidenced. In the second part, with a view towards building a spectroscopic data base, a calculation of the dipolar momentum function was undertaken.
