Binary mixtures of pyridine and ethanol display Raman spectra (111 of pyridine) with significantly different band shapes at different temperatures (between 98 and 368 K). At the lowest temperature these spectra indicate the formation of a hydrogenbonded complex in the slow modulation limit (giving a

It is suggested that the infrared spectra for the C-N stretch of CH&N in methanol and water give evidence for a kinetic averaging of individual bands. The situation is similar to that described in the Letter by Besnard, CabaGo and Yatwood.

We emphasise that a collapsing infrared or Raman band profile with increasing temperature doesnot necessarily imply a movement between the "slow" and "rapid" exchange regimes. We point to systems where band collapse occurs in the slow regime and suggest that for a CH,CN/CH,OH binary mixture the spec
