Quadrupole coupling constant and the direction of the principal axes of EFGtensor of deuterons in KD.(Se0.). are obtained from 40 to -l06'C. It is con-firmed that there exist two symmetrically inequivalent deuterons D(1) and D(2),and D(l) is ordered in the disordered phase. Deuterons D(2) are found to bedynamically disordered in the disordered phase. In the ordered phase, D(1) sitesare divided into two inequivalent groups while the number of D(2) sites remainsunchanged. The splitting of the resonance line of D(I) in the ordered phasedepends on temperature as (7'.. - 7')', where T., is 24.9 'C and f3 is about 0.52 10.08in the temperature from 24.4to 22'C and 0.46.1.0.01 from 22to 3'C. The relationbetween the splitting and the order parameter is discussed.
