Fig. 6.

Comparison between the corrected normalized experimental CHHC buildup curves, i.e., $F_{L,M}^n(t_{\mathit{mix}})$ as defined in Eqs. (19) & (28), for U-¹³C (circles) and U-¹³C^dil_10% (triangles) L-Tyrosine·HCl for (a) C7-C8 and (b) C2-C4. The solid lines in (a) and (b) correspond to SPINEVOLUTION density-matrix simulations of $F_{LM}^n(t_{\mathit{mix}})$ (see Eq. (4)) for 11 spin systems centered around H7, H8 and H2, H4 ¹H nuclei as illustrated in (c) and (d), respectively.
