Supplementary Figure 12: R2 calculated for 13CF, 13CH, 19FC, and 1HC nuclei in 5-19F uracil or uracil as a function of magnetic field strength.

a,b, R2 of 13CF as part of 5-19F uracil (a) and R2 of 5-13CH in uracil (b). c,d, R2 of the uracil 5-19FC uracil (c) and R2 of 5-1HC (d). Here uracil and 5-19F uracil relaxation times are calculated with a rotational correlation time (τc) of 25 ns. Red squares represent the R2 of the TROSY components, and blue triangles represent the R2 of the decoupled resonances. The points are connected by a dashed line to provide visual clarity.
