dc.description.abstractA cell has been designed for studying Raman spectra, of gases under pressure, in the range 100 to 3000 atm. A high resolution grating spectrograph has been used to photographic the rotational and vibrational bands of $H_{2}$, the vibrational line of $N_{2}$, and the $\nu_{1}$ line of $CH_{4}$. Since isotropic scattering does not show ordinary collision broadening, the shifts and broadening of the Q branches of totally symmetric vibrations can be interpreted in terms of perturbations of the vibrational frequencies by intermolecular forces. For the vibrations studied thy maximum of the Q branch at first decreases to a minimum value and then increases as the density of the gas increases. Thus, for $H_{2}$ the frequency perturbation has a minimum value of $-0.6 cm^{-1}$ at a relative density of 275, and increases $+ 1.9 cm^{-1}$ at a relative density of 800. For the heavier gases the frequency perturbations Eire greater. The broadening of the lines is usually of the same order of magnitude as the shifts of the maximum. The significance of those results will be discussed.en_US
