Abstract A discussion of solvent effect upon the streching frequency of Y‐H bonds in correlation with their basicity is reported. The following bonds are studied: O‐H in primary, secondary and tertiary alcohols; N‐H in aliphatic and aromatic amines; and cyclic N‐H where the free electron pair of nitrogen is delocalized in an aromatic π electron system, such as in indole derivatives. The measurements are extended to some indole alcaloïds of known structure.
