✦ Synopsis

The results of new measuremems of the far-infrared optical constant OF hquld waler out 10 4 cm-' a~ 293 K are presented. The+= together with previously published submillimetre wavelength measuremen&. are analysed to show that it is possible to lip the continuous far-infrared-tcrmicrowave absorption spectrum LO classical polar-molecule relaxation theory with added conlribuuons rrom Gaussian oscillator close to 200 and 50 cm-'_ Bolh of these oscillators ha\e been observed in Raman sludles. The 100 cm-' band is well characLerised in infrared measuremenls. but the presenL work represents the first unambiguous identirlcalion of the 50 cm-' band in mrrared observations.
