FTIR study on N-H·hydrogen bonding: N-alkylpropanamides - aromatic donor system

This paper reports the results of an FTIR study in the region of the fundamental NH stretching vibration for N-methyl, N-isopropyl, N-tert-butyl and N-1,2,2-trimethylpropanamide ? aromatic hydrocarbon systems. In addition to the spectroscopic parameters, the equilibrium constant for the 1:1 N-H??? c...

Description
Summary:This paper reports the results of an FTIR study in the region of the fundamental NH stretching vibration for N-methyl, N-isopropyl, N-tert-butyl and N-1,2,2-trimethylpropanamide ? aromatic hydrocarbon systems. In addition to the spectroscopic parameters, the equilibrium constant for the 1:1 N-H??? complexes (at 298 K) are given. U radu se daju rezultati FTIC spektroskopskog isptivanja osnovne valentne N?H vibracije za rastvore cetiri N-alkilpropanamida i sedam aromaticnih ugljovodonika u ugljentetrahloridu. Odredjene su konstante ravnoteze za 1:1 N?H N-H??? komplekse i razmotren je doprinos mehanizma prenosa naelektrisanja ispitivanim vodonicnim vezama.
