摘要：

This paper reports the results of FTIR study of N-tert-butylacetamide in carbon tetrachloride solution and in presence of seven different molecules as H acceptors. The spectroscopic characteristics for N-H center dot center dot center dot O hydrogen bonded complexes are given. Also, the equilibrium constants for 1:1 complex formation, at 25 degrees C were determined by using IR measurements. Frequency shifts of carbonyl stretching vibration nu(C=O) of N-tert-butylacetamide in the same organic H acceptors was also investigated. The wavenumbers of carbonyl stretching vibration nu(C=O) were correlated with the solvent acceptor number (AN) and the linear solvation energy relationships (LSERs). (C) 2012 Elsevier B.V.
