in anhydrous, aprotic solvents.41 Hydrogen bonding changes with temperature and
concentration, and comparison of spectra taken under different conditions also
serves to detect and measure it. As with IR spectra, intramolecular hydrogen bonding
can be distinguished from intermolecular by its constancy when the concentration
is varied. The spin–spin coupling constant across a hydrogen bond, obtained by
NMR studies, has been shown to provide a ‘‘fingerprint’’ for hydrogen-bond type.42
Hydrogen bonds are important because of the effects they have on the properties
of compounds, among them:
