对映体的比旋光度──等值反向范继能（四川师范学院化学系，南充６３７００２）手性化合物对映体的不同性质仅在手性环境或手性试剂作用时才表现出来，手性条件之一的平面偏光对对映体的不同表现——等值反向的比旋光度是实验区别对映体的最方便的方法。但其原因曾经是难... The Specific Optical Rotations of Enantiomers ──The Equivalence Reversal Fan Jieneng (Department of Chemistry, Sichuan Normal University, Nanchong 637002) The different properties of the enantiomers of chiral compounds are only revealed when the enantiomers are chiral or chiral The different behavior of the planar polarizer to the enantiomer, one of the conditions, the specific rotation of the opposite of the value is the most convenient way to experimentally distinguish enantiomers. But the reason was once hard ...
