Sažetak
Hydrogen bonding has a great importance in chemistry and biology. Secondary amides are particulary interesting since the hydrogen bonding of amide group is an important factor in determining the structure of proteins and poypeptides. This paper reports the results of FTIR and NIR study of three caproamides (N-p- fluorphenyl caproamide, N-p-chlorphenyl caproamide and N-p-bromphenyl caproamide) in carbon tetrachloride solution and in presence of diethylether and tetrahydrofuran. The spectroscopic characteristics of the N-H...O hydrogen bonded complexes are given. Also, the equilibrium constants for 1:1 complex formation at 25 degrees Celsius were determined using Mid IR and NIR measurements. Analyzed complexes were compared to complexes of some other secondary amides with same ethers using Wards method cluster analysis.
