We report the first known observation of Raman scattering by oxygen atoms. The (3)P(2)?(3)P(1) and (3)P(2)?(3)P(0) transitions in the electronic ground state that produced Raman shifts of 158 and 227 cm(-1) were detected. These transitions were observed in a fuel-lean atmospheric H(2) + O(2) flame. By comparing the O electronic and O(2) pure-rotational Raman-scattering intensities, we measured the polarized cross sections for the two lines to be 6 +/- 1 x 10(-31) and 4 +/- 1 x 10(-31) cm(2)/sr… CONTINUE READING
