HCNH+
		Nitrogen
	Nuclear Quadrupole Coupling Constants
		in Protonated Hydrogen Cyanide Ion
	Calculation of the 14N eQq in HCNH+ was made on an equilibrium structure derived by Botschwina et al. [1].  Calculated and experimental [2] values are compared in Table 1.  Structure parameters are given in Table 2.
