Frequencies (ν) and integrated intensities A of GeH stretching modes in the IR-spectra of germanes, containing GeCH2Cl and GeCHCl2, have been measured. The doublet character of the ν(GeH) 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
