ABSTRACT
The ground state rotational spectra of eight isotopic species of a weakly bound dimer N(1)N(2) ··· HCN(3) formed between molecular nitrogen and hydrogen cyanide have been detected and measured by the technique of pulsed-nozzle, Fourier-transform microwave spectroscopy. Rotational constants B0, centrifugal distortion constants DJ, and, where appropriate, nuclear quadrupole coupling constants χn(14N) and χ(D) have been determined. For the five isotopic species containing 14N nuclei the results are: An analysis of the B0 values shows that the equilibrium geometry is linear, or nearly so, with the nuclei in the order shown. The DJ values lead to kσ=2.39 N m-1 for the intermolecular stretching force constant while the difference χ1(14N)–χ2(14N) is interpreted in terms of a transfer of 0.016 e from N(1) to N(2) when the complex is formed in the zero-point state.
