Nuclear magnetic resonance spectroscopy experiment generating homonuclear spin-spin decoupled spectra.
Note:
The effect is achieved through the concatenation of partial free induction decays generated with a series of swept adiabatic pulses.
Example:
\(\ce{^{1}H}\) spectrum with no \(\ce{^{1}H},\ce{^{1}H}\) coupling.
