Frequencies (ν) and integrated intenstities A of Ge-H stretching modes in the IR-spectra of germanes, containing GeCH2CL and GeCHCl2, have been measured.The doublet character of the ν(Ge-H) absorption bands has been explained by intramolecular coordination (α-effect) between the chlorine and germanium atoms.The influence of solvents (heptane, carbon tetrachloride, tetrahydrofuran, acetone) on the shape of the ν(Ge-H) absorption bands has been considered.The factors influencing the intensity of coordinated ν(Ge-H) absorption bands have been analysed.The enthalpyof intramolecular coordination (-ΔH) has been determined by spectroscopy.It has been shown that the α-effect enthalpy increaes with the increase of the acceptor properties of substituents bonded to the germanium atom.
