The first ESR spectrum of $Hg^{+}$, observed in Ne, Ar, and Kr matrices is presented, with determination of its magnetic parameters, which exhibited excellent agreement with gas phase values. The ratio of the $g_{n} (g_{n} = \mu_{I}/I)$ values for $^{199}Hg$ and $^{201}Hg$ is shown to vary slightly from $Hg^{+}$ to HgH/HgD. This variation can be attributed to electronic structure differences surrounding the mercury nucleus. Observation of $Hg^{+}$ in a Kr lattice also provides information on the required energy gap between the electron affinity of an isolated species and the ionization potential of the matrix host atom. HgH and HgD were observed in experiments where the plasma discharge was doped with a small percentage of $H_{2}/D_{2}$ gas. The HgH/HgD radicals were observed for the firs t time in a neon matrix, providing a comparison of the various magnetic parameters to earlier argon matrix results. The electronic structure and magnetic parameters of $Hg(CH_{3})_{2}^{+}$ will be analyzed based upon these new matrix results for $Hg^{+}$ and HgH. en_US dc.format.extent 360482 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title MATRIX ISOLATION ESR STUDIES OF Hg RADICALS: $Hg^{+}$, $HgD$, $HgH$, and $Hg(CH_{3})_{2}^{+}$ en_US dc.type article en_US
