英文摘要: Deleterious chlorine fluorescence was found to occur at the same frequency as the Raman scattering of O-2((1)Delta) and O-2((3)Sigma), seriously affecting the O-2((1)Delta) yield measurement in the reaction of chlorine with basic hydrogen peroxide by use of the Raman spectroscopy technique. To solve this problem we have taken advantage of the fact that Raman radiation is always strongly polarized while fluorescence is essentially non-polarized in a gaseous medium. When chlorine utilization of a singlet oxygen generator is 88%, O-2((1)Delta) yield reaches (42.4 +/- 7.4)% with the effect of chlorine fluorescence completely eliminated.
