FIG. 1.

Energy diagram of the different dissociation limits of cation. The energy reference is the trans- energy minimum. The relative energy position of the isomers and designation are from Ref. 17. The energies of the tetratomic electronic excited states are from Ref. 21. The excited and ionization energies of the mono-, di-, and triatomics species are taken from Refs. 30 and 31.

FIG. 2.

One dimensional cut of the 6D-PES of the ground electronic state of trans- along the central NO stretching coordinate . These curves are calculated at the cc-pVQZ/CASSCF, aug-cc-pVQZ/CASSCF, and aug-cc-pVQZ/CASSCF/MRCI levels of theory. The other coordinates are , , in-plane angles , and out-of-plane torsional angle . These curves are given in energy with respect to the trans- minimum.
