Formation of toxic unsaturated multifunctional and organosulfur compounds from the photosensitized processing of fluorene and DMSO at the air-water interface

Generated liquid-phase and gas phase products by ultrahigh-resolution mass spectrometric instruments: Ultrahigh-Resolution Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometer (FT-ICR-MS) and Ultrahigh-Resolution Hybrid Quadrupole Orbitrap Mass Spectrometer which was interfaced with a secondary electrospray ionization source (SESI-HRMS).
