Abstract
Non-rigidity which arises from internal rotational or librational flexibility adds complications in the band shape analysis normally carried out for rigid molecules. In particular, additional band broadening may occur and it is possible that new features may arise in the spectrum if the different processes are separated in time by more than one order of magnitude. Such are the difficulties envisaged in a full analysis that only a few studies have been attempted or published so far. However, such is the importance of molecules, for example with long alkyl chains in biological and industrially important fluids, that future studies will necessarily include attempts to disentangle the intermolecular and intramolecular dynamics. Some very encouraging reports have recently been made. We present a review of the work carried out on alkanes, alkynes, ketones. esters and small rings in an attempt to point to directions of approach which may be viable. We then outline our recent work on the model lubricant molecule 2-ethylhexyl benzoate (EHB) which has been tackled using infrared, far-infrared and Raman methods as well as by 13C NMR. We show that direct evidence for internal rotation/libration is available from properly chosen experiments. We further show how the intermolecular forces are modulated by such motions and how they depend in a unique way on the surrounding environment
