Exchange and crystal fields (CF) acting on {ital R}{sup 3+} ions in {ital R}{sub 2}Fe{sub 14}B were investigated by means of inelastic magnetic neutron scattering. Experimental data for {ital R}=Pr, Nd, Gd, Tb, Dy, Ho, Er, and Tm are reviewed. Molecular fields {ital H} acting on {ital R} ions are calculated using neutron-scattering data for the CF models proposed earlier for these compounds based on single-crystal magnetization measurements. For Gd{sub 2}Fe{sub 14}B the molecular field acting on the Gd{sup 3+} ions was directly determined by inelastic neutron scattering as 2{mu}{sub {ital B}H{ital m}}/{ital k}{sub {ital B}} = 435 K.
