Comments on The rigid-body vibrations of molecules in crystals by Burns, Ferrier & McMullan (1967)
Abstract
The rigid-body analysis of the thermal vibrations in seventeen molecular structures by Burns, Ferrier & McMullan Acta Cryst. (1967), 22, 623-629 has been repeated and major discrepancies have been observed. The sources of errors have been diagnosed and the relevant comments together with the new list of results are reported.
