Five of the six dimer classifications observed by AFM exhibit one or two KL interactions between L5/P5 (purple) and L13/P13 (blue): fully-formed (FF), hook (HK), P-candy, P-Y, and one-leg-out (OLO). The shoulder-to-shoulder (SS) dimer forms through symmetrical tetraloop (cyan)—minor-groove (orange) interactions. The AFM molecular surfaces used for structure calculation were derived from individual particles selected from the AFM image in Fig. 1b.
