A frequently documented NMR spectrum is the 1D 13 C carbon spectrum, which is less sensitive than the 1 H spectrum. Proton decoupling during the FID acquisition can boost its sensitivity (Figure 1).

The preferred method is based on the investigation of signals in the proton NMR spectrum associated with the lipoproteins. Variations in the size, composition, and density of lipoproteins ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...

This technique allows you to obtain concentration information about your NMR sample without the requirement of spiking with an internal calibrant. Selective Excitations Not sure which possible ...
