Abstract
An important advantage of carrying out vibrational spectroscopy in low-temperature matrices is that the bandwidths obtained are much smaller than those in other phases. Thus two bands which have only a small frequency separation may often be resolved using matrix isolation spectroscopy but not by vibrational spectroscopy of, say, a solution at room temperature. While there may be large differences between the vibrational spectra of two conformers for some molecules, more often the vibrational modes are shifted by only a few wavenumbers: thus matrix isolation spectroscopy is potentially a powerful tool for studying conformational isomerism in fairly small molecules. A good illustration of this is provided by ethanol, which exists in trans (I) and gauche (II) conformers (1):
