The geometric inferences for tested acceptors based on two approaches: the first uses the \({{\varvec{\Delta}}}_{{\varvec{C}}}\) order based on the values estimated by global curve fitting in Table 1; the second uses the K orders directly from individual curve fitting, Table 1. Avoiding the confusion, MSTL is represented by the red dotted circles used to approximate the likely locations of MSTL on acceptors
