Webthere has to be an uneven number of protons (and or?) neutrons in order for the nucleuss to have spin. You can only detect nuclei that have spin with the NMR machine. It so happens that over 99% of Hydrogen is H-1 (one is an odd number) and over 99% of C is C-13 (odd number again). So it makes sense that these would be easy to detect.
