The pure rotational and vibration‐rotational Raman spectra of ¹H³H and ²H³H

Abstract

Abstract The pure rotational and vibration‐rotational Raman spectra of the hydrogen species 1 H 3 H and 2 H 3 H have been recorded and analysed. The following rotational constants, vibration‐rotational constants and bond lengths were obtained: magnified image The r e values are compared with those of 1 H 2 , 1 H 2 H, 2 H 2 and 3 H 2 and a weighted mean r e value for the hydrogen molecule was calculated.
