Table 3. Conformational Profile of 14 (A), and 15 (B) (M05-2X/6-311+G**)^a,^b.

^aDihedral angles refer to rotation along the central CC–CC bonds. Each value grid represents the sum of the populations of the nine possible conformations for each defined conformation of the two central CC–CC bond.

^bOnly the most relevant conformers shown (full data: see Figures S3, S4, and Table S2).
