J Hz = ppm x MHz (typically 300, 400, or 500 MHz). High resolution mass spectrometry (HR MS) was carried out using an Agilent LC-ESI-TOF system. Thus the chemical shift of a 13C nucleus in methanol measured at 9.4 T (400 MHz) is the same as that measured at 14.1 T (600 MHz) or that at 18.8 T (800 MHz). We have discussed how the chemical shift of an NMR absorption is affected by the magnetic field B e produced by the circulation of neighboring electrons. The resonance for the methylene protons appear as a quartet at 2.3 ppm. In a 14.1 T magnet the energy levels in a 1H nucleus are split by (and the nucleus is said to resonate at) approximately 600 MHz. As a consequence of the Bn field in a vicinal system, at fixed external magnetic field Bo, a lower frequency will be required to achieve resonance for those molecules which have HX in the state than for those molecules which have HX in the state. The energy difference between the two states is proportional to the strength of the magnetic field and the nuclei’s gyromagnetic ratio (an intrinsic constant for each nucleus). The advantage of using the chemical shift is firstly, that it removes the need to distinguish between MHz frequencies that only differ by several tens of Hz and secondly, that it becomes independent of the magnetic field used. Note that the splitting pattern observed for a particular proton or set of equivalent protons is not due to anything inherent to that nucleus but due to the influence of the neighboring protons. How does the presence of various NMR active nuclei in a compound affect coupling and signal multiplicity? 1H NMR splitting abbreviations: s (singlet), d (doublet), t (triplet), q (quartet), quin (quintet), sex (sextet), h (heptet), b (broad), br u (broad, unresolved).
