The near-IR spectra of thioacetamide were recorded for the investigation of hydrogen bonding between thioacetamide (TA) and N,N-dimethylalkylamides (DMF, OMA, DMP) in chloroform over the range of 5°C to 55°C. The v0 + amide II combination band has been resolved into contributions from monomeric TA, 1:1 hydrogen bonded complex and 1:2 complex by the parameterized matrix modeling method. The association constants <Kc) of the complex have been obtained at various temperatures and used to determine the thermodynamic parameters for the hydrogen bonding by the usual Van't Hoff method. It was found that N ,N-dimethylalkylamide forms less stable hydrogen bonded complex ...
