Abstract
Infrared multiple photon decomposition has been examined for beta -propiola ctone (C3H4O2) using a free electron laser (FEL) in the context of C-13 enr ichment. The compound has an intense infrared absorption band with a peak a t 5.35 mum (1,870 cm(-1)) due to carbonyl stretching vibration. The laser w avelength was changed in the range from 5.40 to 5.60 mum (from 1,852 to 1,7 86 cm(-1) in wavenumber). The observed products were only CO2 and C2H4. The atomic fraction of C-13 in CO2 was found to be 14% in the excitation at la mbda =5.60 mum (1,786 cm(-1)).
