Abstract
The rotational velocity correlation function 〈u(0)·[graphic omitted]ui(t)〉(RVCF) is used to assess two analytical models of the molecular motion which gives rise to far infra-red (2–200 cm–1) absorptions in dipolar compressed gases and liquids. These functions are compared with those derived from the experimental data, and the discrepancies attributed largely to induced, temporary dipoles, the short time (< 2 ps) behaviour of which being more clearly reflected in these short time correlation functions than in the corresponding vectorial ones.Keywords
