What does 1h NMR show?
H NMR is the go-to technique to help identify or confirm the structure of organic compounds or those that contain protons. A solution-state proton spectrum is relatively fast to acquire, compared with other nuclei, and a lot of information about the structure of a compound can be deduced from it.
What information can be obtained from a 1h NMR spectrum?
Generally, the information about the structure of a molecule can be obtained from four aspects of a typical 1H NMR spectrum: Chemical equivalent and non-equivalent protons (total number of signals) Chemical shift. Integration.
