Abstract	In the present investigation examine unsteady free convection flow due to heat and mass transfer of Viscous fluid bounded by an infinite vertical porous plate in rotating system under the influence of a uniform transverse magnetic field of constant strength is studied. The fluid and the plate are in a state of solid body rotation with uniform angular velocity. The temperature and concentration at the plate are assumed oscillatory with time about a constant non-zero mean. The problem is solved by using a regular expansion technique for small value of frequency parameter and perturbation techniques . Approximate solutions for the primary and secondary velocity, temperature and concentration fields are obtained. Expressions for skin-friction at the plate due to primary velocity and secondary velocity, rate of heat and mass transfer are also derived. Numerical calculations are carried out for different values of parameters occurring into the equations of the problem under study and shown through tables
