On the basis of Fourier component analysis of internal rotation around the C-X bond in α- and β-functional derivatives of the type Y-(CH2)n-X (X = NH2, OH; Y = CH3, SiH3, GeH3; n = 1, 2) the nature of intramolecular interactions in these compounds was analysed. Electronic effects of polarisable silyl and germyl groups were found to be dramatically influenced by the molecular conformation.

Fourier analysis of potential curves of internal rotation around C-X and C-C bonds of β-carbofunctional derivatives of the type H3M(CH2)2X (M = X, Si, Ge; X = NH2, OH, F) has been performed and the nature of intramolecular interactions in these compounds is discussed.

Fourier analysis of potential curves of internal rotation around the C-X bond in α-carbofunctional organosilicon compounds of the type Y-CH2-X (X = NH2, OH; Y = SiH3, Si(CH3)3) has been used to study the character of intramolecular interactions in relation to the mechanism of the so-called α-effect. The results obtained are in accordance with previous conclusions based on the analysis of orbital correlation diagrams.

On the basis of Fourier analysis of internal rotation curves for α-carbofunctional derivatives of Group IVb elements the effect of protonation of parent molecules on the nature of electronic effects of methyl, silyl and germyl substituents is discussed.
