摘要: Abstract The conformation of alkylamino chains has been analyzed by using isolated C–D stretching vibrations. compounds studied are N-methylpiperidine-2,6-d2, N-ethylpiperidine-1′-d1, N-propylpiperidine-1′-d1, N-butylpiperidine-1′-d1, N,N-dimethylpentylamine-1-d1, N,N′,5,5-tetramethylhexahydropyrimidine-2-d1, N,N-dimethylbutylamine-2-d1, N,N-dimethylpentylamine-2-d1 and N,N-dimethylhexylamine-2-d1. observed wavenumbers for different conformations at positions the chain have correlated linearly to bond lengths calculated ab initio molecular orbital methods. depend significantly on in close vicinity bond. Isolated vibrational spectroscopy great potential being used conformational analysis functional biological substances.
