【分享】一本关于NMR弛豫的专著 Practical NMR relaxation for chemists [PDF,209p]

核磁共振技术(NMR)

  • 论坛上不少朋友对NMR驰豫的问题感兴趣,现上载一本关于NMR弛豫的专著供有兴趣者研读。
    该书虽然是为化学家所写,但还是需要有一些物理学和NMR背景知识。该书对在实验室工作的NMR工作者是有用的。
    这本书可能是教授化学家NMR驰豫技术的第一本专著。2005年出版,还是比较新的。

    以前对弛豫就不怎么懂,平时也不操作核磁,所以也不要求
    研读研读此书,抑或释解疑惑!
    谢谢!

    弛豫的应用这些年来逐渐广泛流行起来.
    未来可以鼓励每个课题组, 报导与分析所涉及化合物的弛豫情况, 了解其相关理化变化与涵义.
