Answer 1

Answer:

The interaction between the spin magnetic moments of the different sets of H atoms in the molecule under study, is known as spin-spin coupling. It is imperative that a minimum of 2 sets of protons are present in adjacent positions. The magnetic spins of these resonating nuclei interact with each other and affect each other’s precession frequencies. The effective magnetic field (Beff) experienced by neighboring protons as a result of magnetic spins thereby affect the chemical shift values. [5] In addition to the chemical shifts, the nature of the peaks in the NMR spectrum is also affected.
