Abstract

This paper reports the results of an FT-IR and NIR study of N-methylformamide in carbon tetrachloride solution in presence of ethers as the O-electron donors, i.e., diethyl ether (DEE), diisopropyl ether (DiPE), methyl t- -butyl ether (MtBE), dibutyl ether (DBE), dipentyl ether (DPE), tetrahydrofuran (THF) and tetrahydropyran (THP). The spectroscopic characteristics of the N-H???O hydrogen bonded complexes are given. In addition, the equilibrium constants for 1:1 complex formation were determined at 25?C using Mid-IR and NIR measurements.
