Absorptions Between 3000 and 5500 cm-1 of cyclic O4+ and O4- Trapped in Solid Neon



Marilyn E. Jacox, Warren E. Thompson


Recently, gas-phase absorptions in the 3000 to 4300 cm-1 spectral region have been assigned to combination bands built on (v1 + v5) of ground-state cyc-O4+. Other gas-phase experiments identified an electronic transition of cyc-O4- complexed with an argon atom between 4000 and 5300 cm-1. Absorptions that correspond closely to these two groups of bands have been observed in neon-matrix experiments in which both cyc-O4+ and cyc-O4- are trapped at 4.3 K in solid neon. The rresults are compared with the gas-phase data, and the proposed assignments are considered taking into account the results of isotopic substitution.
