Gas phase isomerization of documentclass{article}pagestyle{empty}begin{document}$ left[{{rm C}_{{rm 10}} {rm H}_{{rm 14}} } right]_{}^{_.^ + } $end{document} ions generated from adamantanoid compounds

documentclass{article}pagestyle{empty}begin{document}$ left[{{rm C}_{{rm 10}} {rm H}_{{rm 14}} } right]_{}^{_.^ + } $end{document} ions have been generated from a number of adamantanoid compounds, both by ionization and ionization followed-by fragmentation. Metastable ion abundance ratios of competitive reactions indicate the decomposition of these ions from common structures in all cases.
