Gated decoupling power

Figure 4,9. Possible schemes for applying proton decoupling when observing a heteronucleus, (a) Gated decoupling (coupled spectrum with NOE), (b) inverse-gated decoupling (decoupled spectrum without NOE) and (c) power-gated decoupling where the rf is applied at two different powers (decoupled spectrum with NOE).

High resolution solution state NMR spectra were obtained using a 10 mm broadband probe on a Bruker WM 500 spectrometer with a 45° flip angle, power-gated broadband decoupling and a relaxation delay of 6 seconds. [Pg.235]

The DD experiment can be applied either continuously or gated [15]. In the latter experiment, often termed inverse-gated decoupling, broad-band irradiation is applied only during acquisition. In this manner, the total power consumption is smaller, and this condition leads to less heating of the sample. [Pg.356]
