Yes, carbon-12 (12C) has fewer neutrons than carbon-13 (13C). Carbon-12 has 6 neutrons, while carbon-13 has 7 neutrons.
Proton decoupling in 13C NMR spectroscopy is achieved by irradiating the sample with radiofrequency pulses that flip the nuclear spins of the protons, effectively decoupling them from the carbon nuclei. This eliminates the splitting caused by proton-carbon coupling, resulting in a simpler and easier-to-interpret 13C NMR spectrum.
The nuclear notation of an atom with 6 protons and 7 neutrons would be written as carbon-13, denoted as 13C. This indicates the total number of protons and neutrons in the nucleus of the atom.
13C label atoms are carbon atoms that have been replaced with the stable isotope carbon-13. This labeling technique is commonly used in metabolic studies to trace the fate of specific carbon atoms within molecules. By tracking the movement of 13C label atoms, researchers can gain insights into metabolic pathways and nutrient utilization in biological systems.
If the element in question is carbon, it has 6 protons, whether it's 12C, 13C, 14C, or any of its other 12 known isotopes.
