The superposition model is used to investigate the crystal field parameters, B_{kq} of Cr^{3+} in lithium potassium sulphate. The zero field splitting parameters D and E are then determined using microscopic spin Hamiltonian theory and compared with the experimental values obtained by electron paramagnetic resonance. Both zero field splitting parameters D and E evaluated theoretically are in good agreement with the experimental values. The results suggest that the Cr^{3+} ion occupies substitutional K^{+} site in lithium potassium sulphate.
