Nitrogen quadrupole coupling constants for HCN and H2CN +: Explanation of the absence of fine structure in the microwave spectrum of interstellar H2CN+
Nitrogen 14 quadrupole coupling constants for H2CN+ and HCN are predicted via ab initio self-consistent-field and configuration interaction theory. Effects of electron correlation, basis set completeness, and geometrical structure on the predicted electric field gradients are analyzed. The quadrupol...
