We performed the neutron inelastic scattering experiments on YbX(X = N,P,As) in order to study crystal field splitting in this series of compounds. We found that, in the frame work of the effective point charge model, the ligand charges obtained from the fourth order crystal field parameters are 2.0e(YbN), 3.0e(YbP), 4.3e(YbAs) using the Dirac-Fock values for the radial integrals. The obtained sixth order crystal field parameters B6's are found to be one order of magnitude greater than the values of the effective point charge model.
