Detailed calculations have been performed of multiphonon relaxation rates of optical excitations in Nd-doped LiYF 4 and Pr-doped CsCdBr 3 crystals in the frameworks of the exchange charge model of the crystal fields and rigid ion harmonic models of lattice dynamics. It is shown that the empirical en
