Infrared spectra of all isomers of polymethyl-substituted benzoic acids were recorded in the carbonyl and hydroxyl regions in tetrachloromethane at various concentrations and interpreted in terms of conformation. According to a plot of #(C=O) of the monomeric form vs Hammett substituent constants ',
## Abstract AmideโI and II vibrations of ฮฑโhelix have been treated on the basis of the perturbation theory in a dipoleโdipole approximation. The infinite helix and its finite fragments have been considered as models. The calculated infrared spectra for the infinite helix are in good agreement with
The assignments of 13C and 1H NMR spectra for madeirane triterpenes are reported. The assignments were made on the basis of two-dimensional homonuclear 1H, 1H (COSY) and of 1H detected 1H, 13C heteronuclear correlation (HMQC) and also from a series of one-dimensional selective INEPT experiments. 19
