Scientists have isolated the two different forms of water molecule for the first time.前不久，专家初次成功分离出来出二种有所不同方式的水分子。Water molecules were known to exist as two distinct isomers, or types, based on their slightly different properties at the atomic level.根据分子水准上略微有所不同的特性，不明的水分子能够以二种有所不同的“异构体”种类不会有。By separating out the two isomers, researchers were able to show that they behave differently in the way that they undergo chemical reactions.根据分离出来出二种异构体，科学研究工作人员必须证实他们在进行化学反应时能够展示出出有有所不同的不负责任。In basic terms, water molecules consist of a single oxygen atom bonded to a pair of hydrogen atoms.简而言之，水分子是由两个氢原子和一个氧分子键合而成的。
However, they can be further subdivided based on a property of the nuclei at the hearts of the hydrogen atoms - their spin.可是，他们能够依据氢原子关键“磁矩”的特点更进一步细分化。While they arent spinning in the sense we would understand, this property of hydrogen nuclei does affect the rotation of the water molecules themselves.尽管这不是大家一般讲解实际意义上的旋转，但氢核的这类特性显而易见不容易危害水分子自身的旋转。
If the nuclear spins of the two hydrogen atoms in water are oriented in the same direction, it is called ortho-water. If they are arranged in different directions, it is known as para-water.假如水分子中的两个氢原子核磁矩以完全一致的方位趋向，则称之为因此以水分子。假如她们异向磁矩，则称之为胜水分子。Given that the isomers are very similar, it has been particularly challenging to separate them out. But co-author Prof Stefan Willitsch and his colleagues succeeded in doing it using electric fields.由于异构体十分相仿，因此将他们分离出来十分具有趣味性，但Stefan Willitsch专家教授和他的朋友顺利地运用静电场进行了水分子提取。
They were then able to investigate how the different forms of water reacted with another chemical.接着，她们就必须科学研究有所不同方式的水分子与另一种化工品的反映状况。They used ultracold diazenylium ions (a form of nitrogen) for this test. The researchers found that para-water reacted about 25% faster with the diazenylium than ortho-water.她们用以氮离子（一种氮的方式）进行了此项检测。科学研究工作人员寻找，与因此以水分子相比，胜水分子化学反应速率提高了25％上下。
Because the rotation of H2O molecules is affected by the nuclear spin, different attractive forces act between the partners in this chemical reaction.因为水分子的旋转遭受核磁矩的危害，因此在这类化学反应中，有所不同的诱惑力在相互之间反映中间起了具有。Prof Willitsch said the research could help improve control over other kinds of chemical reaction: The better one can control the states of the molecules involved in a chemical reaction, the better the underlying mechanisms and dynamics of a reaction can be investigated and understood.Willitsch专家教授答复，此项科学研究能够帮助提升对其他类型化学反应的操控：“我们可以更优地操控化学反应中水分子的情况，不利更为深入分析和讲解反映的潜在性体制和动力学模型。
