Web29 de jan. de 2024 · On an NMR instrument where protons resonate at 300 MHz and 13 C nuclei resonate at 75 MHz, phosphorus resonates at 32 MHz. In 31 P − N M R experiments, the reference standard used to determine the 0 ppm point is usually phosphoric acid (tetramethylsilane, the standard 0 ppm point for 1 H - and 13 C − N M R, doesn't have a … WebSummary: NMR spectroscopy relies on detecting the precession rates of nuclear magnetic moments, which is sensitive to chemical environment. In HSQC, we let the magnetization sit with each nucleus for some amount of time, thus sampling the chemical environment of both nuclei. The result is a signal that we can plot on both proton and nitrogen ...
