[Collective dynamics of globular proteins and impulse methods of nuclear magnetic resonance]

The theory of the NMR spin echo on globular proteins signals envelope is developed, based on the model description of collective excitations of macromolecules in terms of the continuous media mechanics. The influence of internal motions is taken into account with the suggestion of the local connection between the spin-spin relaxation and deformational rotations of separate parts of the molecule. The results of the calculations are compared with experimental data.
