Figure 5. Build-up curves.

Figure 5

Magnetisation build-up curves obtained using (a) PARIS (N = 1/2), (b) PARIS-xy (m = 1)(N = 1/2), and (c) PARIS (N = 2) recoupling schemes for different cross-peaks of U-13C-,15N-L-histidineInline graphicHInline graphicO, at Inline graphic = 30 kHz and Inline graphic = 11.74 T. Each recoupling scheme was applied for a fixed mixing-time period (90 ms) using different RF amplitudes of 7.3, 16, 24, 30, and 40 kHz. Inline graphic values calculated for individual cross-peaks according to Eq. 1 are plotted as a function of RF amplitude. All Inline graphic values are normalised with respect to the maximum value yielded by PARIS (N = 2) using a RF amplitude of 40 kHz. Data points are joined with straight lines to guide the readers' eyes.
