Observation of a heterogeneous source of OCIO from the reaction of CIO radicals on ice

Article Abstract:

A heterogeneous source of several chlorine oxides, in particular OCIO and CICIO2, from CIO radicals passed over water-ice surfaces at low pressures is demonstrated. CIO radicals are generated in a flow system and reaction products are monitored by UV-vis absorption spectroscopy and time-of-flight mass spectrometry using electron-impact and resonance-enhanced mulitphoton ionization, respectively.

Two-photon absorption cross section determination for fluorene derivatives: analysis of the methodology and elucidation of the origin of the absorption processes

Article Abstract:

A new approach for a two-photon absorption (2PA) cross section determination of various fluorene derivatives is described. The results show that these fluorenes exhibit large absorption cross-section values and hence can be easily used in several nonlinear optical applications.
