Effect of H/D isotope substitution on polarizability of methanol molecules

E. V. Ivanov* and V. K. Abrosimov

The electron polarizabilities (α0•1024/cm3 molec.–1) were estimated from the data on refractive indices and molar volumes of H/D isotopomers of methanol at 25 °C using the Lorentz—Lorentz formula: 3.265 (ÑÍ3ÎÍ), 3.260 (ÑÍ3OD), 3.235 (CD3OH), and 3.231 (CD3OD). A relationship between the isotope effects for α0 and volume (packing) changes in the structure of liquid methanol induced by deuterosubstitution in the methanol molecule was proposed.
