It has been recently shown that mechanical milling can amorphize D-glucose without any mutarotation, giving rise to an anomerically pure amorphous sample. We have taken advantage of this exceptional possibility to study the kinetic of mutarotation in the amorphous solid state. The investigations have been performed in situ by time-resolved Raman spectroscopy. The results reveal an unexpected coupling between the mutarotation process and the structural relaxations involved in the glassy state.
最近有人指出，机械球磨可以使 D-葡萄糖非变旋地非晶化，从而得到旋光纯度极高的非晶样品。我们利用这一特殊的可能性，在非晶固态中研究了变旋作用的动力学。这项研究是通过时间分辨的拉曼光谱进行的。结果表明，变旋过程与玻璃化态中涉及的结构弛豫之间存在着出人意料的耦合。
