Experimental results are presented on stimulated Raman scattering of short pulses of approximately 100 ps duration in H
2, D
2, and CH
4, both in capillary waveguides and in a tight focusing geometry. Experimentally determined thresholds are in good agreement with calculation. Low thresholds (

J) are observed in CH
4and preliminary results using a mode-locked dye laser as pump indicate a useful source of tunable short pulse radiation in the near infrared.
