Vacuum-ultraviolet Photoion Spectrum of Vinyl Chloride Near Ionization Threshlod
Abstract:
The photoionization efficiency curve (PIE) of C2H3Cl+ formation from C2H3Cl has been measured in wavelength region 105.0- 130.0nm, by using synchrotron radiation single- photon ionization and a quadrupole mass spectromemter as a detector. A series of peaks in region 106.0-117.0nm arise from Rydberg autoionization converging to A2A' state of the vinyl chloride ion, the average quantum defects are δ(ns) = 1.87, δ(np) = 1.51,δ(nd) = 0.22 respectively. The Rydberg transitions of π(2a") → 4d, π(2a") →5d, π(2a")→6s, π(2a") →7s have been assigned also.
