Cryogenic solids serve as hosts for transient and highly reactive species. As the widest band gap materials, they allow for efficient stabilization of ions and electrons. Ionic and neutral species including those of atmospheric and extraterrestrial interest were characterized using matrix-isolation spectroscopy and DFT computations. IR-spectroscopy of mass-selectively deposited ions with cyano groups, formed upon electron-impact ionization of tetracyanoethylene and acetonitrile precursors, yielded information about their structure. Studies of neutral molecules in various matrices provided data on formation of novel xenon-carbon compound and also contributed to the characterization of organic azides. Activation spectroscopy methods based on the detection of thermally and photon-stimulated emission of electrons from Ne and Ar solids gave insight into charge transfer processes, trapping mechanisms and charge stability in rare gas matrices.
