✦ Synopsis

The high-resolution absorption spectrum of the D 2 O molecule was recorded with the Fourier-transform intracavity laser absorption spectrometer in the region 12 570-12 820 cm -1 where the band 4ν 1 + ν 3 is located. Transitions belonging to the 4ν 1 + ν 3 band, and the bands 3ν 1 + 2ν 3 and 3ν 1 + 2ν 2 + ν 3 , of which the up states are strongly interacted with that of the 4ν 1 + ν 3 , were assigned in the recorded spectrum. Up state energy levels were fitted to derive effective spectroscopic parameters, which reproduce majority of the assigned transitions within the experimental accuracy.

The 3 1 and 3 1 ϩ 3 bands of propyne have been recorded at Doppler-limited resolution by Fourier transform spectroscopy and intracavity laser absorption spectroscopy, respectively. The two bands show a mostly unperturbed J rotational structure for each individual K subband. However, as a rule the K
