摘要

Ternary complexes of HNO_3 ? HCl ?H_2O were investigated by ab initio calculations with aug-cc-pVDZ and aug-cc-pVTZ basis sets. The results are analyzed in terms of structures, energetics, and infrared vibrational frequencies. In all minima, neither HNO_3 nor HCl becomes ionized. The contribution of the nonadditivity effect, which is significant for hydrogen-bonded clusters, is bigger for the cyclic structures in whichHNO_3 acts as a proton donor toHCl, although the global minimum contains HNO_3 donating its proton to a H_2O molecule.
