✦ Synopsis

The spin density matrix formalism has been applied to rotational-echo double-resonance (REDOR), transferred-echo double-resonance (TEDOR) and two-dimensional (2D) TEDOR experiments in order to obtain an expression for the signal intensities. TEDOR spectra of lSN-labeled glycine were measured with different dipolar evolution times. ZD-TEDOR spectra were measured of doubly labeled glycine-2-13C,15N and of r5N-labeled glycine. Both the TEDOR and the 2D-TEDOR spectra were readily obtained although the 2D-TEDOR experiment on r5N-labeled glycine used a lot of machine time. Even though the "N-l-r3C dipolar coupling is relatively small (200 Hz), the 1-C resonance can still be observed.
