In quantum spin liquid states, the fractionalized spinon excitations can carry fractional crystal symmetry quantum numbers, and this symmetry fractionalization distinguishes different symmetry-enriched spin liquid states with identical intrinsic topological order. In this work we propose a simple way to detect signatures of such crystal symmetry fractionalizations from the crystal symmetry representations of the ground state wave function. We demonstrate our method on projected spin liquid wave functions on the kagome lattice, and show that it can be used to classify generic wave functions. Furthermore our method can be used to distinguish several proposed candidates of spin liquid states on the kagome lattice.
