Abstract
NMR spin echoes are calculated for a rotator consisting of three spin-(1/2) nuclei whose three-particle wave function obeys C(3) symmetry. On decomposing the nuclear dipole-dipole interactions in terms of irreducible operators of the representations of the group C(3) it is found that for spins belonging to the A-representation, the echo amplitude is maximized for a RF pulse sequence. The dependences of the echo formation on the orientation of the rotor and on the strengths of the dipolar interactions and the magnetic field inhomogeneities are discussed.
