科学家发现水分子其实有两种类型|首页

scientists have isolated the two different forms of water molecule for the first time。最近科学家们成功地分离了两种不同形式的水分子。water molecules were known to exist as two distinct isomers,or types,based on their slightly different properties at the atomic level.By separating out the two isomers,researchers were able to show that they behave differently in the way that they undergo chemical reactions.In basic terms,water molecules consist of a single oxy gen atom bonded to a pair of hydrogen atoms。

简单地说,水分子是两个氢原子和一个氧原子结合在一起的。However,they can be further subdivided based on a property of the nuclei at the hearts of the hydrogen atoms-their spin。但是,根据氢原子核心的不同,While they arent spinning in the sense we would understand,this property of hydrogen nuclei does affect the rotation of the water mole culleculation水分子的两个氢核磁矩向完全相同的方向倾斜,如果它们有异向磁矩,就被称为乘数分子。given that the isomers are very similar,It has been particularly challenging to separate them out . but co-author prof Stefan willits ch and his ch因为异构体非常相似,所以分离是非常困难的,但Stefan Willitsch教授和他的同事利用电场顺利地分离水分子。

they were then able to investigate how the different forms of water reacted with another chemical。然后,我们需要研究不同形式的水分子如何对不同的化学物质做出反应。they used ultra cold diazenylium ions(a form of nitrogen)for this test . the researchers found that para-water reacted about 25研究人员表示,与水分子相比,because The rotation of H2O molecules is affected by The nuclear spin,different attractive forces act between The partners in this chemical reaact_首页。
