(a) PHRONESIS experiment for simultaneous acquisition of ten 3D spectra using ¹H detected ultrafast MAS. The GENETICS‐AI pulses (gray rectangles) are applied on CA and CO to encode multiple pathways. (c–h) Sequential assignment of GB1 protein using ten 3D spectra (Table S1) acquired with 65 kHz MAS. (h) Summary of unambiguously resolved 3D cross peaks picked from each experiment. Cross peaks obtained from only the (H)CANH‐(H)CA(CO)NH pair yielded correct automatic assignments for only 36 % of NH spin systems, while 100 % accuracy was achieved if CO(i‐1) and CO(i) correlations were also included.
