Abstract

An approach to the study of the spatial structure of cyclic compounds with low conformational energies of substituents is considered. For the 1H NMR spectra of cyclotetrasilazanes, as an example, it is shown that the temperature dependences provide a valuable information relating to configuration of substituents. Extrapolated to infinite temperature, the spectra become essentially additive.
