Thomas-Reiche-Khun populations in X-CH3 and X-C2H5 series of molecules

Calculations of nuclear electric shieldings, equivalent to dipole moment geometric derivatives, and related to atomic polar tensors, are presented for X-CH3 and X-C2H5 molecules with X = NH2, OH and F. The electric shielding tensors satisfy a constraint for the electrostatic equilibrium, i.e., the m...
