Parameters

atom (paramagpy.protein.CustomAtom) – the active nuclear spin for which relaxation will be calculated must have attributes ‘position’ and ‘gamma’
atomPartner (paramagpy.protein.CustomAtom) – the coupling parnter nuclear spin must have method ‘dipole_shift_tensor’

Returns

value – the CCR differential line broadening in Hz

Return type

float
