A variationhyphen;perturbation method has been employed to calculate the dynamic dipole polarizability for the ground state of the hydrogen molecule. The explicit correlated electronic wave functions were used. The averaged values of agr;(ohgr;) and ggr;(ohgr;) for several vibrationhyphen;rotation states of HD and D2are presented. Similar values for H2have also been calculated and were used to test the efficiency of the method and the validity of the assumption applied in the present calculation. The agreement of the present theoretical results with the existing experimental data is found to be satisfactory.
