The vibration‐rotation Raman spectrum of P₄

Abstract

Abstract The vibration‐rotation Raman spectrum of the ν 2 fundamental band of P 4 has been recorded photographically using a spectrograph with a reciprocal linear dispersion of 1.36 cm −1 mm −1 . Analysis of the spectrum gave the following values for the vibration and rotation constants and the PP bond length: magnified image
