A search for the HF2 and HClF neutral free radicals isolated in argon matrices
摘要:
A systematic search has been carried out for the neutral species FHF and FHCl isolated in argon matrices at 14 K. The synthesis of these species was attempted by the photolysis of F2 in the presence of either HF or HCl, either concurrent with, or after deposition into the low temperature matrix. Infrared spectra of these samples gave no evidence for the formation of a species of the form FHF, while evidence was demonstrated for a weakly bound complex between HF and Cl, but with a very different spectrum and structure than the corresponding FHCl− anion. These results are in general agreement with the detailed theoretical calculations that have been performed on these systems.
