Abstract
The doublet structure of v(C=O) bands in the IR absorption spectra of some trimethylsilylesters of carboxylic acids XCOOY [X = CCl3, CCl2H, CClH2, C(CH3)3, CH2Si(CH3)3] indicates conformational heterogeneity. The conformations of these esters were studied by analyzing the changes in IR spectra caused by solvent and temperature effects.
