Absorption and Ionization Coefficients of Vinyl Chloride

Abstract

Absorption coefficients of vinyl chloride were measured by a photoelectric method at many wavelengths in the region 1075–2000 Å, and photoionization yields were obtained in the region 1075–1240 Å with an ion chamber. Many bands were identified as members and their vibrational companions of four Rydberg series and one other electronic transition. These Rydberg series and the photoionization curve yielded the same ionization potential of 10.00±0.01 eV.
