Samson, F.F. Marmo, K. Watanabe Title: Absorption and photoionization coefficients of propylene and butene-1 in the vacuum ultraviolet Journal/Source: J. Chem. Phys., 36, 783-786, (1962); http://link.aip.org/link/doi/10.1063/1.1732610 Data: table, diagram Energy/Wavelength range: 105 - 200 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: 0.04 - 0.2 Torr Phase: gas pH: Comments: Absorption and photoionization coefficients of propylene and butene-1 vapors have been measured by the photoelectric technique in the spectral region 105-200 nm. Two Rydberg series were observed in propylene yielding series limits of 9.74 and 9.80 ev. From the photoionization coefficient curves ionization potentials of 9.73 and 9.80 ev were observed for propylene, and 9.58 ev for butene-1.
