Chiral handedness翻译
WebIn general, if you have a small molecule with no sp3 centers in the molecule, the molecule is planar. But there are many exceptions. Here are a few common ones: - Water is planar. The oxygen is sp3 but there are only 3 atoms so there's nothing to stick out of the HOH plane. - Allene is not planar. WebFeb 24, 2016 · A previous analysis 7 revealed that the chiral energy makes E handedness-dependent. Interestingly, Emilie Jué and colleagues 6 find only v 0 to be handedness-dependent . Based on this observation ...
