Most of the density functionals are able to predict well the angles (Table ) The picture changes again completely when looking at the vibrational frequencies (Table , Figure ). Note that the DFT frequencies were computed at the CCSD(T) geometries; this allows to separate clearly the effect of accuracy for geometries (Tables ) from the accuracy for frequencies (Table ). Here the hybrid functionals in all the different guises are observed at the upper half of the list, with the O3LYP hybrid functional performing best (MAD 8.1 cm -1 ), followed closely by B97 (8.4 cm -1 ), and B97-1 (8.7 cm -1 ). The best composite is again r2SCAN-3c (9.4 cm - 1 ). The best MGGA-hybrid functional is now TPSSh (MAD 9.5 cm -1 ), TMHF is the best local hybrid again (MAD 10.1 cm -1 ), M06-L is the best metagga functional (MAD 10.2 cm -1 ), RC04 the best LDA functional (10.3 cm -1 ), HSE06 the best range-separated hybrid functional (MAD 11.1 cm -1 ), OPBE the best GGA functional (MAD 11.5 cm -1 ), wLH23tde the best range-separated local hybrid (MAD 13.1 cm -1 ), and PWPB95 the best double-hybrid functional (MAD 21.2 cm -1 ). Most of the list of 100 DFAs show MAD values for the vibrational frequencies that remain below 20 cm -1 , and 68 are within 10 cm -1 from the best performing one.
