An NMR experiment used to measure spin-spin (T2) relaxation times of quadropolar nucei by acquiring multiple spin echos with the intensity decay of the echos proportional to T2. In the solid state, this is also used to enhance sensitivity of low gyromagnetic ratio nuclei by collapsing the intensity of the 'full' spectrum into discrete 'spikelets'/peaks. The intensities of the peaks vary according to T2 and the envelope described by these peaks represents the full, static spectrum.
