✦ Synopsis

The HCO radical has been detected by degenerate four wave mixing (D4WM) spectroscopy following 308 nm photolysis of CH,CHO. Spectra have been obtained for the (0, I 1,O) 6 (0, 0,O) and (0, 10,O) + (0, 0,O) vibronic transitions ofthe A%"&% *A band system, and the effects of Renner-Teller rovibronic coupling to the dissociative 2 state have been investigated. The most important observation is the enhanced spectral resolution that is obtained in D4WM spectroscopy, which results from the Lorentzian cubed line profile that is predicted for degenerate four wave mixing spectroscopy in the limit of extreme homogeneous broadening (stationary atom limit). We estimate the detection limit to be approximately I x 10" cm-s quantum state-'.

The peculiar size enhancement of the degenerate four-wave mixing (DFWM) signal of weakly confined excitons is elucidated by the use of the microscopic nonlocal theory of the nonlinear response. It is clarified that the high coherence of excitons plays an important role to enhance the internal field,
