Abstract  Based on the analysis of group-chain scheme, the crystal-field-level fitting of Nd3+: LiYF4 has been carried out, in which the Nd3+ inos occupy positions with site symmetry S4. The RMS deviation of energy-level fitting is 12.8cm-1. Using the obtained wave functions, g-factors of the fround state are calculated,which are g=2.067 and g=2.631, in good agreement with the experimental values(g=1.978 and g=2.554). The method proposed turns out to be effective in the study of spectral properties of localized centres in laser crystals.
