A simple pulse sequence, based on a double 13 C echo and off gated proton decoupling, is shown to yield four subspectra (C, CH, CH 2 and CH 3 ) from linear combinations of four different experiments. This procedure has two advantages: (1) experimental simplicity, keeping instrumental adjustments to a minimum and (2) acquisition of the four experiments under identical lengths of the evolution period, thus eliminating any spurious effects due to transverse relaxation.
