The latter is done here, for a total of 100 density functionals coming from ten classes (LDA, GGA, MGGA, hybrid, MGGA hybrid, range-separated hybrid, local hybrid, range-separated local hybrid, double hybrid and composites). In general, the density functionals are remarkably accurate for bonds and angles, with average deviations of 0.027 Å for all bonds, 0.77° for angles; dioxygen bonds are more difficult to get right, with an average deviation from the coupled cluster of 0.058 Å, more than twice as large as the deviation for all bonds. The cause for this is difficult to pinpoint onto ingredients of DFAs or specific chemical bonding patterns. The frequencies from coupled cluster calculations are off by ca. 10-20 cm -1 , where it should be noted that the well-known Hartree-Fock instability can significantly affect the frequency values for open-shell systems.
