DEXTROROTATION在英语中的意思是什么？

背景和左派

Dextrorotation and levorotation

指旋转和左旋是指旋转平面偏振光的性质。 如果光线接近观察者时顺时针旋转，则称为右旋转，右旋转的光。 如果光线接近观察者时逆时针旋转，则光线会向左旋转。 具有右旋的化合物称为右旋或右旋，而具有左旋的化合物称为左旋或左旋。 具有这些性质的化合物据说具有光学活性并由手性分子组成。 如果手性分子是右旋的，其对映体将是左旋的，反之亦然。 事实上，对映异构体将使平面偏振光旋转相同数量的角度，但反方向。 除了直接测量实际样品的旋光外，只能通过详细的计算机建模，直接从其绝对配置确定给定的手性分子是左旋还是右旋。 也就是说，“R”和“S”立体中心都具有右旋或左旋的能力。

Dextrorotation and levorotation refer to the properties of rotating plane polarized light. If the light rotates clockwise as it approaches an observer, this is known as dextrorotation, light with a rotation to the right. If the light rotates counterclockwise as it approaches the observer, then the light exhibits levorotation, rotation to the left. A compound with dextrorotation is called dextrorotatory or dextrorotary, while a compound with levorotation is called levorotatory or levorotary. Compounds with these properties are said to have optical activity and consist of chiral molecules. If a chiral molecule is dextrorotary, its enantiomer will be levorotary, and vice-versa. In fact, the enantiomers will rotate plane polarized light the same number of degrees, but in opposite directions. Apart from direct measurement of the optical rotation of an actual sample, it is only possible to determine whether a given chiral molecule will be levorotatory or dextrorotatory, directly from its absolute configuration, via detailed computer modeling. That is to say, both "R" and "S" stereocenters have the ability to be dextrorotatory or levorotatory.
