✦ Synopsis

Most of a large gap in the laboratory rovibrational spectrum of H + 3 between the ν 2 fundamental and the first overtone has been filled using a recently automated color center laser spectrometer which scans between 3000 and 4200 cm -1 . A narrow-bore liquid-nitrogen-cooled He/H 2 discharge is used to produce rotationally and vibrationally hot H + 3 . With the high-temperature plasma and the improved sensitivity of the spectrometer we were able to probe very high-energy rovibrational levels, several in the region of the barrier to linearity where theoretical calculations are expected to break down.

The high-resolution infrared spectrum of monoiodoacetylene measured with a Bruker IFS 120 HR Fourier transform spectrometer in the spectral range of 2000 -3000 cm Ϫ1 has been studied in detail. The strongest bands observed in the wavenumber region investigated are the C-C stretching fundamental 2 (2

We have measured the Fourier transform spectrum ( FTS ) of two isotopomers of hydrogen cyanide ( H 12 C 14 N and H 12 C 15 N ) from 500 to 10 000 cm 01 . The infrared data have been combined with earlier published microwave and submillimeter-wave measurements. From this analysis new vibration -rotat
