Any particular member can be specified as being enantiomeric or diastereomeric in relation to the other members of the set . 就组内其他成员来说，任何特定的成员都能被确定为对映体或非对映体。
2.
Short excited state lifetime and low activation energy for reactions in the excited states leave little room for manipulating the diastereomeric transition state when the photochemical reactions occur in solution 最新的研究表明，采用含手性空间或经手性修饰的微环境可以使光化学反应的立体选择性大大提高。
