Comparison of HP (black, circles) and LP (magenta, triangles) NCA SPECIFIC-CP for microcrystalline f-MLF. a) NCA SPECIFIC-CP magnetization buildup. b,c,d) NCA SPECIFIC-CP transfer efficiency dependence on experimental conditions: ¹H decoupling rf field during SPECIFIC-CP (b), ¹⁵N chemical shift offset (c), and ¹⁵N rf mis-set (d). Each datapoint was calculated by integrating the CA region from the corresponding spectrum acquired by accumulating a total of 8 transients. The data in each panel is independently scaled to only compare the behavior of each NCA SPECIFIC-CP matching condition.
