Abstract
The $C_{3}H_{5}$ cyclopropyl radical has been generated in a slit supersonic discharge source and the infrared spectrum in the CH stretching region recorded via a direct absorption difference frequency spectrometer. The radical is generated by expanding a dilute (1\%) mix of cyclopropyl bromide in a diluent of Ne/He. Precursor and radical absorption are differentiated by simultaneous gated detection and gated discharge current. Transitions observed around $3118 cm^{-1}$ and $3041 cm^{-1}$ are tentatively assigned to the lone CH stretch and the asymmetric $CH_{2}$ stretchs, respectively. A more detailed rotational assignment is currently in progress and the results will be reported, providing both structural information and a detailed view into the inversion tunneling of the lone hydrogen through the radical center.
