## Abstract The electric field gradient in the hydrogen molecule has been calculated by diagrammatic manyβbody perturbation theory (MBPT) in Gaussian basis sets. The procedure through third order in electron correlation gives a value for the field gradient of 0.34041 a.u., which is 0.8% greater tha
