✦ Synopsis

Difluorocarbene (CF,) has been observed by time-resolved diode laser absorption spectroscopy following excimer-laser photolysis of C,F,. A band strength of 2.8 x 1 O-i' cm molecule-' for the u3 band may be inferred from the absorption measurements, assummg a quantum yreld &* = 2 from C,F, photodissociation. This agrees well with other experimental estimates, but is somewhat lower than theoretical predictions.
