For all warheads, there is an energetic minimum at r ≈ 1.85 Å for all the PES scans in Figure , with the same stability trend observed between the three rotamers. Across all warheads, the PES scans corresponding to the Θ min ≈ 50 ing to the Θ min ≈ 50 • rotamer, and this can be seen by the overlapping PES scans corresponding to these two rotamers after the point of discontinuity for all four warheads in Figure . In fact, the coefficient of determination (R 2 ) values between the overlapping regions of the synclinal PES scans were calculated to be 1.0 for each warhead, showing the high degree of correlation between the two regions.
