Knight, L. B. An experimental procedure for ESR studies of rare gas matrix isolated molecular cation radicals: 12CO+, 13CO+, 14NH3+, and 15NH3+. J. Chem. Phys. 1982, 77, 1750-1750.
A generally applicable technique is described that enables the ESR study of molecular cation radicals isolated in neon matrices at 4 K. Preliminary evidence indicating the possible use of the method for the study of ionâ€neutral reactions is briefly discussed. The â€™â€™gaslikeâ€™â€™ nature of the trapped matrix ions is demonstrated by a comparison with gas phase results for 13CO+, one of the few radical cations studied by high resolution microwave spectroscopy. Application of the method to the following radical cations is presented in this report: 12CO+, 13CO+, 14NH3 +, and 15NH3 +. The ions are produced during neon matrix deposition by photoionization with an open tube neon discharge source (16.8 eV).
