Infrared spectra in the 0--H and N-H stretching regions have been used to measure the interaction between halide ions (Cl-, Br-, Ias tetra-alkylammonium salts) and water or N-methyl acetamide (NMA) in tetrachloromethane. Formation constants for the monosolvates (at 22.5"C) have been estimated. Frequency shifts were approximately proportional to the free energy of hydrogen-bond formation and to the widths of the monosolvate bands. Formation constants for the monoaquo complexes and the NMA coniplexes were similar to those previously reported for the corresponding methanol solvates ; however, the sensitivity of the N-H frequency was less than that of the 0-H frequency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
