Figure 2From: Unravelling a fulvene based Replicator: Experiment and Theory in InterplayConcentration-time-curves and NMR data for all products. a) Black circles show the autocatalytic reaction, empty squares the reaction in the absence of recognition sites using A'. The rate of formation of NX is lower than the formation of NX' in the background reaction as precursors are consumed predominantly by autocatalytic pathways leading to NN. b) One set of pyridine protons allowed to extract concentrations of all three products from NMR measurements. The assignment was supported by the calculated shifts shown here. c) Cutout of a ROESY spectrum showing all three NH-protons. A coupling indicating chemical exchange is only visible between NN and NX.Back to article page
