The 1H (proton) NMR spectra are one of the most common NMR experiments. Apart from the tritium, the proton is the most sensitive nucleus and usually yields sharp signals. Proton NMR is very useful depending on its sharp signals even though its chemical shift range is narrow. 1H NHR determines the structure of molecules by used proton. The 1H NMR spectra usually provide the following information: 1h nmr spectra database https://www.creative-proteomics.com/pronalyse/1h-nmr-spectra-service.html
