We report experimental values of the group velocity dispersion (GVD) of water and methanol at 800 nm. We find GVD(800)(water) = (25(71 +/- 0(5) fs(2) mm(-1) and GVD(800)(methanol) = (33(56 +/- 0(5) fs(2) mm(-1). These were measured by sending 50 fs, 800 nm pulses with various amounts of chirp through a glass cell filled with a solution of fluorescein in these solvents and recording the production of visible light from the side using a commercial digital camera. This simple setup also gives quantitative information on the duration of our pulses and lets us check independently the correct operation of our grating- based pulse compressor. Results are compared to FROG measurements.
