Abstrakt: 1.The IR and UV spectra and the13C NMR spectra have been studied, and calculations of the frequencies and normal modes of vibration of compounds with the general formula (C2H5)3MC= CXC2H5 (M=Si, Ge, Sn; X=0, S) have been carried out.2.In the system of bonds there is “continuous” conjugation of the M and X heteroatoms through the triple bond. Here the oxygen atom functions as an effective p donor with respect to the triple bond, whereas the sulfur atom functions as a weak p acceptor.
