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.
