“The Raman spectra of gaseous $H2$, $D2$, $O2$, $N2$, $CO$ $CO2$, $CH4$, $C2H2,H2O,NH3,SiH4,PH3$ have been recorded photoelectrically using a multireflection gas cell (1 - 2 atmos.) and a White Raman spectrometer. Pure rotational spectra and some vibration-rotation bands of relatively high signal to noise ratio have been obtained with slit widths of $1.5-5$ $cm-1$. Intensities and depolarization ratios of the Raman bands have been obtained and a simple model useful for estimating the Raman intensity of the totally symmetrical fundamental in hydrides is discussed.”
