An analysis of the heat and mass transfer effects on an unsteady flow of a micro-polar fluid over an infinite moving permeable plate in a saturated porous medium in the presence of a transverse magnetic field, radiation absorption and thermo-diffusion were studied. The governing system of partial differential equations was transformed to dimensionless equations using suitable dimensionless variables. The dimensionless equations were then solved analytically using perturbation technique to obtain the expressions for the velocity, micro-rotation, temperature and concentration. With the help of graphs, the effects of the various important parameters such as the translational velocity, micro-rotational velocity, temperature and concentration fields within the boundary layer entering into the problem were discussed. Also the effects of the pertinent parameters on the skin friction coefficient, couple stress coefficient and rates of heat and mass transfer in terms of the Nusselt number and Sherwood numbers were presented numerically in tabular form. The results showed that the observed parameters have a significant influence on the flow, heat and mass transfer.
