Abstract
This paper describes the investigation of molecular diffusion at liquid-solid interface by visualizing the concentration distributions of two-liquids mixed in microscale. Imaging of the concentration distributions was achieved by measuring the Raman intensity excited by the evanescent wave generated at liquid-solid interface. In the calibration experiment, it is confirmed that the linear relationship between the concentration and the intensity of Raman scattering was obtained. In the further experiment, D_2O and H_2O will be mixed in T-shaped microchannel. Imaging of the concentration distributions in the mixing field will be performed by using the calibration curves.
