✦ Synopsis

Accurate theoretical dipole moments (/I,) have been computed for the X2n ground states of Si-H+ (0.118 D), Ge+ H-(0.085 D) and Sn+H-(0.357 D). The trend down the periodic table is regular and follows that expected from the electronegativities of the group IV atoms. The dipole moment of 1.24 k 0.1 D for GeH recently derived by Brown, Evenson and Sears from the relative intensities of electric and magnetic dipole transitions in the 10 pm spectrum of the X 21f state is seriously questioned.
