Crystal field analysis of the energy level structure of lithium yttrium fluoride doped with trivalent dysprosium was performed. Assignment of absorption lines in experimental spectrum of absorption was made in a wide spectral region: from IR to UV. Crystal field parameters for the whole series of trivalent rare earth ions in LiYF4 crystal were obtained. The values of the intermediately coupled Lande g-factor were calculated and used to estimate the EPR g-factors g||, g⊥ for LiYF4:Dy3+.
