✦ Synopsis

The Raman spectra of fatty acids, fatty acid methyl esters and several membrane lipids are analyzed in the 1300 cm -1 region. The ratio of peak intensities at 1303/1267 cm -1 varies linearly with the ratio of methylene to vinyl groups in the hydrocarbon chain. This parameter should be useful for estimating the degree of unsaturation in isolated lipids and lipids in membranes.

The HDO absorption spectrum was recorded in the 13 165-13 500 cm Ϫ1 spectral region by intracavity laser absorption spectroscopy. The spectrum (615 lines), dominated by the 2 2 ϩ 3 3 and 1 ϩ 3 3 bands, was assigned and modeled leading to the derivation of 196 accurate energy levels of the ( 103) and

New laboratory measurements are presented for the near-infrared and visible spectrum (8600-15 000 cm -1 ) of water vapor. Spectral line parameters, principally intensities and air-broadening coefficients, are derived from Fourier transform spectroscopic measurements at high resolution (0.03 cm -1 ),
