Abstract
A method for high resolution NMR (=nuclear magnetic resonance) measurements using the application of excitation pulses and the acquisition of data points, whereby a dwell time Δt separates the acquisition of two consecutive data points, which is characterized in that one or more tickling rf (=radio frequency) pulses of duration τare applied within each dwell time Δt, and that the average rf field amplitude of each of the tickling rf pulses approximately fulfills the conditionω=ωτ/Δt=πJ wherein J is the scalar J-coupling constant and ω=γBwith γ being the gyromagnetic ratio and Bbeing the strength of the magnetic component of each tickling rf pulse. This method is effective in decoupling homonuclear couplings.
