In a more complex molecule such as protein, the spinspin couplings between 1 h 1 h or 1 h c atoms are difficult to interpret using just the standard 1 h nmr technique. It is analogous to proton nmr 1 h nmr and allows the identification of carbon atoms in an organic molecule just as proton nmr identifies hydrogen atoms. In conclusion, 1h and c are the only two nuclei that are routinely. The techniques applied to the measurement of c nuclei are different to those for protons. Only one isotope is observed at a time because the spectrometer transmits and receives over a very limited frequency range. As understood, triumph does not suggest that you have fantastic points.
