FTIR study of N–H ... p hydrogen bonding: N-alkylpropanamides – aromatic donor systems

Abstract

This paper reports the results of an FTIR study in the region of the fundamental NH stretching vibration for N-methyl, N-isopropyl, N-tert-butyl and N-1,2,2-trimethylpropanamide – aromatic hydrocarbon systems. In addition to the spectroscopic parameters, the equilibrium constant for the 1:1 N–H ... p complexes (at 298 K) are given.
