A similar and transferable result is found for dihedral angles investigated for a subset of 13 molecules for which excitation leads to a significantly bent excited-state structure. While dihedral angles of corresponding GS geometries are consistently predicted to describe a planar geometry for all auxiliary and primary basis set sizes, the bending angle of the excited state is more accurately described when increasing the cardinal number of the auxiliary basis from double-to triple-zeta size. Again the effect of additional polarization functions as included within the largest tz2p basis is negligible. A plot for the ADMM error in dihedral angles analogous to Figures and is given in the SI. Taking a summarizing look at the corresponding statistical data of Table , listing mean deviations (MDs), mean absolute deviations (MADs), and standard deviations (STDs) for bond lengths, angles, and dihedral angles of ES geometries optimized within the various primary and auxiliary basis set combinations, emphasizes again the impact of the chosen auxiliary basis: while MADs of the dzp basis amount up to 1.4 pm for bond lengths and up to 1.2 • or 2.1 • for bond and dihedral angles, tzp results are converged with remaining deviations of 0.2 pm / 0.3 • / 0.3 • . The deviations are negligibly small in comparison to the error of 0.5 to 1.0 pm that was found for bond lengths for hybrid functionals in comparison to highly accurate coupled-cluster results. Error distributions are relatively broad for the dzp auxiliary basis and nearly equally narrow for tzp and tz2p basis sets. MDs and MADs are of the same magnitude, indicating that the dzp auxiliary basis predicts bonds that are consistently too long. This trend is in agreement with the conclusions of Ref., with the latter stating that global and range-separated hybrids yield slightly too short bonds and that functionals with a rather small amount of exact exchange show negative mean signed errors.
