(A) Selected spectra of the GTA triplex during experiments of transfer of magnetization from water at 1°C. The exchange delay, τ (s), for each spectrum is indicated. The labeled imino proton resonances show changes in intensity during transfer of magnetization from water. (B) Dependence of the intensity of the G₂₇ imino proton resonance on the exchange delay, τ, in experiments of transfer of magnetization from water.
