Interpretation:
Out of the two given protons, which proton is shielded to a greater extent and which proton requires higher frequency radio waves to cause a spin flip is to be explained.
Concept introduction:
When H atoms (surrounded by electrons) are subjected to
Chemically distinct protons are surrounded by different electron distributions and therefore have different values of

- True or False : The difference in energy, ΔE, between alfa (+1/2) and beta (–1/2) spin states of a proton is independent of the strength of the applied magnetic field. Could you explain detail?arrow_forwardConsider the following lanthanide (III) ionsA) Nd(III) B) Gd(III) C) Dy(III)For which of the above ion(s), is the magnetic moment closest to the spin only value?arrow_forwardCalculate the frequency separation of the nuclear spin levels of a 13C nucleus in a magnetic field of 15.9 T given that the magnetogyric ratio is 6.73 × 107 T-1 s-1.Ans = ______ MHz. (Note: because the magnetogyric ratio of 13C nucleus is only about 1/4th of that of a proton, the frequency of resonance is also only about 1/4th of the proton resonance frequency in the same instrument.arrow_forward
- 1. Spin-spin coupling between two hydrogen nuclei is mediated through chemical bonds. In the ¹H NMR, this coupling is usually observed through ______ bonds.arrow_forwardWhy is 133C-133C spin-spin splitting not observed in ordinary organic compounds?arrow_forwardHow will E for an isolated 13C nucleus compare with that of a 1H nucleus?arrow_forward
