The enhancement of stimulated Raman scattering (SRS) of week-gain Raman modes is demonstrated in pendant drops by overlapping the Stokes of the Raman modes with Rhodamine 640 dye gain profile. After obtaining the optimal dye concentration and the pumping intensity, the technique is used to investigate the minority species in binary mixture pendant drops. The limit of detectable concentration for the minority species, methanol in methanol-ethanol and ethanol in ethanol-water mixtures, is greatly reduced.
