WebAnd that is not just how many protons in total, you can see specifically how many protons you have for the given signal, which is coming, for example, from an aromatic ring. Depending on how many substituents are on the ring we can have a monosubstituted, disubstituted or a pentasubstituted ring which changes the number of protons on the ring ... WebSep 4, 2024 · Proton density weighted sequences. Given that nuclear magnetic resonance of protons (hydrogen ions) forms the major basis of MRI, it is not surprising that signal can be weighted to reflect the actual density of protons; an intermediate sequence sharing some features of both T1 and T2.
