title: Correct values of the rotation barriers of 1,8-ditolylanthracenes.
abstract: The rotation barriers of two 1,8-ditolylanthracene derivatives have been measured by accurate line-shape simulation of their variable-temperature NMR spectra. Both values were found to be more than twice as large as those previously reported in the literature.
