Paper Abstract

A spontaneous Raman scattering system has been developed which can monitor the yield of a COIL singlet oxygen generator performance in real time. This approach permits one to directly measure [O2(a1(Delta) )] and [O2((Chi) 3(Sigma) )] simultaneously by monitoring their Raman spectra on the same ICCD array. This technique is reviewed and the major sources of error discussed and analyzed. The uncertainty in the Raman cross section limits the accuracy of the measurement technique. With the current uncertainty of the Raman cross section, this technique gives an accuracy of better than 2.5 percent in the yield measurement at 50 percent yield.
