The complete molecular Hamiltonian contains a term which is not invariant to inversion of electronic coordinates through the molecule center. This gives rise to the axial asymmetry of electronic charge. Treating the term as a perturbation it is found that the $^{1}\Sigma_{g}$ electronic ground state is perturbed only by states of $^{1}\Sigma_{n}$ symmetry. It is assumed that only the lowest such state (the B state) contributes. Averaging over the Morse eigenfunctions of the first three vibrational levels, the values $8.89 \times 10^{-4}, 8.84\times 10^{-4}, 8.78\times10^{-4}$ Debye unit are obtained for the permanent moment. The dipole is directed along the internuclear axis with the proton end relatively positive. en_US dc.format.extent 81160 bytes dc.format.mimetype image/jpeg dc.language.iso en en_US dc.publisher Ohio State University en_US dc.title THE DIPOLE MOMENT OF HD en_US dc.type article en_US
