摘要：
Difluorocarbene (CF2) has been observed by time-resolved diode laser absorption spectroscopy following excimer-laser photolysis of C2F4. A band strength of 2.8×10-17 cm molecule-1 for the ν3 band may be inferred from the absorption measurements, assuming a quantum yield {A figure is presented} from C2F4 photodissociation. This agrees well with other experimental estimates, but is somewhat lower than theoretical predictions. © 1990.
