The equivalent Raman scattering cross section of NO (nitric oxide) referred to O2 (oxygen) and N2 (nitrogen) was obtained experimentally. Furthermore, it is shown that it is possible, using the Raman effect, not only to detect small concentrations of nitric oxide in water saturated nitrogen but also to obtain quantitative measurements of NO independent of the presence of other species.
