Comparison of different 2D NMR techniques for 13 C, 31 P correlation

Three different experimental techniques are compared to find the most efficient protocol for 2D 13 C, 31 P correlation spectroscopy. It is shown that the best signal‐to‐noise ratio is given by the polarization transfer experiment for 31 P detection and by the HMQC experiment for 13 C detection. Applications of these techniques for 13 C, 31 P correlation of β‐nicotinamide adenine dinucleotide (NAD + ) and a mixture of three different mononucleotides are described.
