The ionization data of a neutral molecule are crucial to model the energy deposition and dissociative ionization process. We study theoretically the electron impact ionization process and report on the dissociative ionization cross sections of the tu

The electron impact partial ionization cross-sections of molecules such as methane, water and nitromethane are computed using a modified form of the binary encounter Bethe (BEB) formula. The modified form of the BEB model works on rescaling the molec

Our primary goal was to measure the NO (A) photoproduct appearance energy and ground-state dissociation energy of the N2-NO complex. We recorded velocity map ion images of NO photofragments resulting from the dissociation of the N2-NO complex excited

Air-liquid interfacial processing of volatile organic compound photooxidation has been suggested as an important source of secondary organic aerosols. However, owing to the lack of techniques for studying the air-liquid interface, the detailed interf

We report a comprehensive vacuum ultraviolet (VUV) photoionization study of the nitrogen dioxide dimer (NO2)2 by using a state-of-the-art method of double imaging photoelectron photoion coincidence (i2PEPICO) spectroscopy at synchrotron SOLEIL. We fi

Hydroperoxides from the ozonolysis of alkenes, in addition to Criegee intermediates, have been proposed as an atmospheric source of OH radicals in the absence of sunlight, but have remained largely elusive due to their reactivity. A weak peroxide bon
