Answer 2

1. n(fine lines) = 5

2. n(hyperfine lines) = 30

Explanation:

• We have MN(II) $\implies$ $n (unpaired \ e^-) = 5, I \ (given) = \frac{3}{2}$
• therefore $n(fine \ lines) = n (unpaired \ e^-) = 5$
• and          $n(hyper-fine \ lines)\\ \\= n(unpaired \ e^-)\times (2nI+1)\\ \\= 5 \times (2*1*5/2 \ +1) = 30$
• Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for evaluating materials with unpaired electrons.
• The essential concepts of EPR are similar to those of nuclear magnetic resonance (NMR), with the exception that electron spins are energised instead of atomic nuclei.
• EPR spectroscopy is a powerful tool for studying metal complexes and chemical radicals.
• EPR was found for the first time in 1944 at Kazan State University by Soviet scientist Yevgeny Zavoisky, and it was independently discovered by Brebis Bleaney at the University of Oxford at the same time.
