Example of conformational diversity in dipole moment in the molecule omegacsd_CNBPCT reflecting anti-parallel carbonyl (left - rmsd45) or parallel carbonyl groups (right - rmsd92), with B3LYP-D3BJ def2-TZVP computed dipole moments ranging from 1.41D to 9.78D,  respectively.  The two geometries differ by only 1.3 kcal/mol  at the B3LYP-D3BJ def2-TZVP level, with the more polar conformer (right) stabilized by an intramolecular hydrogen bond. Using DLPNO-CCSD(T) cc-pVTZ, the less polar conformer (left) is more stable by 0.3 kcal/mol.
