(A) Representative ¹³C relaxation data of hydrocarbons for LCPs formed by MO at 35 wt% hydration, and (B) plot of corresponding ¹³C R₁ and ¹³C-{¹H} hetNOE along the hydrocarbon chain, excluding the carboxylic carbon (C1, Fig. 3A), measured at ¹H magnetic field strength of 600 MHz and 298 K. The pertaining minimum (1.15) and maximum (2.61) ¹³C-{¹H} hetNOE values, at the field strength of the data acquired, expected for a completely rigid (S = 1) and flexible (S = 0) C-H bond respectively, are indicated by dotted lines. The same colour code as in Fig. 5 is adopted for hydrocarbons with degenerate ¹³C chemical shifts due to symmetry around the olefinic double bond.
