Electron momentum distribution (EMD) on trans-stilbene single crystal projected along  direction has been studied by using positron two dimensional -angular correlation of annihilation radiation (2D-ACAR). The projected EMD is explained with respect to the molecular arrangement in the plane. The EMD features reflected the delocalized electronic states in  direction. The results of EMD mapping did not show a characteristic ellipsoidal distribution at lower momentum region (LMR) as observed in trans-stilbene projected to  direction at room temperature. The LMR region exhibits a hexagonal contour projected to  direction.
