Distribution of the RI-MP2/CBS relative energies of rSPSOM models of GpU (black), ApA (red), and UpC (blue) experimental platform structures (i.e., idealized rSPSOMs are not included). The relative energy, reported along the horizontal abscissa, is partitioned into twelve bins of 1.0 kcal.mol−1 width. The curves correspond to standard Gaussian normal distributions based on the mean values and standard deviations, with infinitesimal bin width. The green dashed line at 0.0 kcal.mol−1 denotes the energy of the A-RNA reference state.
