Raman Scattering Diagnostics in the Presence of a 1203

An experiment was conducted to determine the effect of A1203 on the Raman scattering from Nj and 0in the presence of A1_0~. It was found that within the experimental accuracy, no effect could be determined. Furthermore, v.he presence of A1-0., could also be ascertained using the Raman effect, although no quantitative results are as yet available. This research was supported by the Advanced Resec.rch Projects Agency of the Department of Defense and was monitored by the U.S. Army Research Office-Durham, under Contract No. DAHC04-o9-C-0077 This work was accomplished by a cooperative effort of Dr. M.H. Bloom, Dr. P. Khosla, Mr. J. Bornstein and the author, and was prepared for presentation at the "Review and Planning of ARPA Program on Rocket-Plume Diagnostics" held at the Institute for Defense An?lyses, December 14, 1972. Professor of Aerospace Engineering.
