The Effect of Conditions Applied to Determine on the Rotatory Direction

Liu Chunyun Yin Yuying (Beijing Institute of Petrochemical Technology, Beijing 102600) Cheng Jiyuan (Graduate School. Academia Sinica,Beijing 100039)  
The rotatory direction determined under different conditions will be change for some optically active molecules. Because their conformations have been changed under different conditions. The change of the conformation will lead to the change of the helical direction in molecular structure. So that it results in change of the rotatory direction. This does not disagree with the rule of helix theory. When the changes of conditions applied to determine can not have influence on the conformation in molecular structure, the rotatory direction will not change.
