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 first NMR spectra were first published in the same issue of Physical Review in January of 1946. Bloch and Purcell were jointly awarded the Nobel Prize in Physics in 1952 for their discovery of ...
