The results of two separate studies of the complex between NO and N 2 are reported. The (1 ϩ1) REMPI spectrum of the Ã ←X transition of the complex between NO and N 2 is presented of improved quality over that reported previously, and the appearance of the spectrum is discussed. The results of high-level ab initio calculations ͓RCCSD͑T͒/aug-cc-pVQZ//QCISD/6-311ϩG͑2d͔͒ on the X 2 ⌸ state are also reported. The indications are that the NO moiety is more freely rotating in the complex than is N 2 , and that a wide angular space is sampled in the zero-point energy level. The appearance of the REMPI spectrum suggests that the Ã 2 ⌺ ϩ state is ͑close to͒ linear, and RCCSD͑T͒//QCISD calculations on the Ã state, using Rydberg-function-augmented basis sets, suggest that the lowest energy linear isomer is the ON•N 2 linear orientation. It is clear, however, that the understanding of this complex, and its spectroscopy, is far from complete, and will be challenging.

“…However, observation of free radicals is extremely difficult because of their very short lifetimes and low concentrations in the gas medium. Thus, once the challenges to radical generation could be overcome, spectroscopy of free jets represents an advantageous means of probing the natures of free radicals [1].…”

“…1 Thus, the characteristics and structures of transient species could at least describe chemical reactivities and aid our understanding of reaction dynamics at the transition state. Many reaction intermediates can be formed by eliminating atoms or groups of atoms (radicals) from stable molecules to produce free radicals, and thus, comparisons of the structures of starting molecules and resulting free radicals allow us to explore the effects of bond cleavage on molecular structure.…”

ABSTRACT. Well-resolved vibronic emission spectra were recorded in the visible region from the corona discharge of precursor alkylbenzenes in a technique of corona excited supersonic expansion using a pinhole-type glass nozzle. From the observed spectra, we found the evidence of the presence of benzyl-type radicals generated by dissociation of C-C or C-H bonds of alkyl group. After identification of benzyl-type radicals formed in the corona discharge, we suggest that energy densities in alkyl chain play a crucial role in determining the bond dissociation during corona excitation.
