Abstract
The vibrational Raman band of liquid chlorine was studied to shifts of 130 cm-1 from the band centre. The second moment of the rotational component is about 20 per cent above the theoretical value. Good exponential decays of the second order orientational correlation function are observed from >0·2 ps. The resulting relaxation times are well reproduced by a microviscosity equation, and the results are in reasonable accord with N.M.R. relaxation times. Intermolecular torques, as derived from second and fourth intensity moments, compare well with results from molecular dynamics calculations.
