    • An NMR teaching method and apparatus incorporating pieces representative of chemical fragments. Each piece has the number of sides corresponding to the number of bonds present around the central atom. Bonds to hydrogen are curved while bonding sides are flat. The presence of concavities and convex tabs on the bonding sides indicates bonding of the respective piece to a mating piece that causes splitting of the NMR peak. The shape of concavities on each piece is indicative of the chemical fragment of the respective piece while the shape of the convex tab of the respective piece is indicative of the chemical fragment of the mating piece. First and second bonding indicators can be used to replace the convex tabs. When presented with a spectrum, a student user can select the necessary pieces using data from the spectrum. Once selected, the student user can then assemble the pieces to determine the identity of the unknown molecule in the NMR spectrum.
    • 包含代表化学碎片的片段的NMR教学方法和装置。 每一块具有与中心原子周围存在的键数相对应的边数。 与氢的键合是弯曲的,而粘合侧是平的。 在粘合侧上存在凹凸和突片,表明各片与配合片的结合,导致NMR峰分裂。 每片上的凹部的形状表示相应片的化学片段,而各片的凸形片的形状表示配合件的化学片段。 可以使用第一和第二粘合指示器来代替凸起的凸起。 当呈现频谱时,学生用户可以使用来自频谱的数据来选择必要的部分。 一旦选择,学生用户就可以组装这些片段,以确定NMR光谱中未知分子的身份。
