 Title: GAS PHASE RAMAN SPECTRA OF WATER AND THE WATER-TRIMETHYLAMINE COMPLEX Creators: Gilbert, A. S.; Bernstein, H. J. Issue Date: 1973 Publisher: Ohio State University Abstract: The spectra were obtained with a multipass cell and an argon laser as exciting source. The scattering cross-section (relative to nitrogen) of the symmetric stretching mode of water vapor was measured at room temperature. Increasing the vapor pressure by heating to about $100^{\circ} C$ allowed fine structure on the Q-branches of $H_{2}O$ (symmetric stretching) and HDO (hydrogen stretching) to be resolved, and the vibrational-rotational and pure rotational bands of $H_{2}O$ and $D_{2}O$ were also recorded. The asymmetric stretching and bond angle deformation modes could not be observed with certainty; the latter is at least 500 times weaker than the symmetric stretching mode. Water and tri-methylamine have been found to form a one-to-one complex in the gas phase.
