Abstract
Cycling sidebands arising from broadband decoupling of I-S heteronuclei are separated from the decoupled I spectra investigated in a 2D pulse sequence wherein I excitationis followed after the interval δ+twith refocusing π pulseoperating on the I spins. After I excitationthe Jcoupling is inverted by π pulseand immediately following the π pulsedecouplingis turned on and maintained while signal acquisition in the interval tis initiated at δ+tafter pulseDouble FT yields a 2D spectrum with sidebands completely displaced to diagonal locii, or alternatively the time domain data may be accumulated into respective tlocations by effectively summing over tto yield a single dimensional spectrum free of cycling sidebands.
