The use of coherent Raman beats for the detection of nuclear coherences in solids from nuclei with hyperfine couplings to unpaired electron spins is discussed. The coherent Raman beats do not require refocusing of the electron spins and therefore are not strongly affected by spectral diffusion of the electron spins. Several methods for generating nuclear coherences using a single microwave pulse, two microwave pulses, or a combination of microwave and radiofrequency pulses are discussed. One‐dimensional and two‐dimensional spectroscopies for the measurement of hyperfine interactions in solids are proposed.
