We have used 2 H-nmr to study backbone dynamics of the 2 H-labeled, slowly exchanging amide sites of fully hydrated, crystalline hen egg white lysozyme. Order parameters are determined from the residual quadrupole coupling and values increase from S 2 Ο 0.85 at 290 K to S 2 Ο 0.94 at 200 K. Dynamica
