Knight, L. B.; Miller, P. K.; Steadman, J. Fast atom bombardment (FAB) generation of neutral and charged reactive intermediates for rare gas matrix isolation spectroscopic studies. An ESR investigation of 111,113CdOH and 111,113Cd+ in neon and argon matrices at 4 K. J. Chem. Phys. 1984, 80, 4587-4587.
An experimental arrangement is presented which allows the combination of neutral atom bombardment in the 3â€“10 keV range with the rare gas matrix isolation technique for generating and trapping reactive intermediates and cation radicals for electron spin resonance(ESR) and other spectroscopic investigations. The potential of the experimental procedure for studying metal surfacereactions is discussed. Neon and argon matrix results are reported for the bombardment of several gaseous and metal samples. The 1 1 1 , 1 1 3CdOH radical has been characterized by ESR and compared with previous findings for CdCN, CdF, and CdH. Neon matrix measurements for CdH and Cd+ have been obtained with the FAB method which allow a comparison to be made with previous argon matrix findings. This represents the first magnetic data comparison of neon and argon matrix results for a metal hydride type radical (MH) and a cation radical. These comparisons are especially important for gauging the â€˜â€˜gasâ€likeâ€™â€™ nature of matrix results for such highly reactive radicals.
