INTENSITY IN THE RAMAN EFFECT V. PHOTOELECTRICALLY RECORDED RAMAN SPECTRA OF SOME SIMPLE MOLECULES IN THE GAS PHASE

Abstract

“The Raman spectra of gaseous $H_{2}$, $D_{2}$, $O_{2}$, $N_{2}$, $CO$ $CO_{2}$, $CH_{4}$, $C_{2}H_{2}, H_{2}O, NH_{3}, SiH_{4}, PH_{3}$ 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.”
