abstract = {The rotational barrier in benzaldehyde was evaluated using
DFT methods and CCSD. Compared to experimental values, the
calculated values are typically a factor 2 too high.
Evidence is provided this also applies to N-methylbenzamide.
The results once more suggest that molecules comprising a
benzene ring with a pi-conjugated substituent form a special
problem with respect to calculation of the rotational
barrier around the C(sp2)-C(aryl) bond. It must be concluded
that current DFT functionals cannot properly handle such
barriers. Conversely, successfully describing these
rotational barriers may be an appropriate and stringent test
for new functionals. (C) 2002 Published by Elsevier Science
