Both one dimensional 2H MAS NMR and two dimensional (EXSY) NMR were used to study lanthanum sub-stoichiometric trideuteride (LaD2.85) at room temperature. Re mark - ably narrow (8 and 10 Hz) intense lines were observed at 3.06 and 2.97 ppm in addition to two additional (31 and 35 Hz wide) at 2.62 and 1.92 ppm. The shifts were measured with respect to the 2H NMR line in PMMA (poly(methylmethacrylate)). The positions and intensities of the lines are discussed in terms of the order-disorder situation in the octahedral D-sublattice of the lanthanum matrix.
