Absorption coefficients of ethylene have been measured in the region 1065–2000A. The most intense absorption has been found to occur in the bands near 1700A where the k values are near 1400 cm−1. Two main continua were found having maxima at 1620 and 1250A, with k values of 750 cm−1 and 625 cm−1 at the respective maxima. The oscillator strengths are 0.34 for the 1620A continuum and 0.30 for the 1250A continuum. The ionization region was observed beginning at 1180A. A number of new bands were observed and some of them were classified as members of the first Rydberg system observed by Price and Tutte. A discussion of these results in the light of Mulliken's theoretical work is presented.
