WebJan 30, 2024 · The table gives a range of 20 - 30, and that's where it is. One final important thing to notice. There are four carbons in the molecule and four peaks because they are all in different environments. But they aren't all the same height. In C-13 NMR, you cannot draw any simple conclusions from the heights of the various peaks. WebLes spectres RMN 1H confirment la conformation C4v en couronne.
