The spatial and angular Goos-Hanchen (GH) and Imbert-Fedorov (IF) shifts are examined for fundamental Gaussian beam (633 nm) reflected from a monolayer of MoS(2)using the 'Stokes polarimetric' technique. This technique enables us to promptly determine the magnitudes of the reflection coefficients and their relative phase differences which gives the optical beam shifts. The GH and IF shifts are measured with different polarization basis along with varying angle of incidence. This is a precision technique depending only upon the polarization components of the light beam and is quite independent of the fluctuations of the light intensity. The response of GH and IF shifts for MoS(2)substrate is significant and thus may open up new possibilities in the optical applications of 2D materials.
