Abstract

Absorption spectra of the ν₁ + ν₃ and 2ν₂ + ν₃ bands of HDO and the ν₁ + ν₂ + ν₃ and 2ν₁ + ν₂ bands of D₂O have been recorded from 6380 to 6600 cm^-1 by using single-mode distributed feedback semiconductor lasers (DFB lasers) with an experimental accuracy of about 0.004 cm^-1. An analysis of the HDO spectrum was successfully carried out by taking account of both Coriolis and Fermi interactions between the (101) and (021) states. In the D₂O molecule, the Coriolis interaction between the (111) and (210) states was clearly observed and a preliminary set of the rotational and coupling constants was determined.
