Q36 · CSIR-NET Chemistry, June 2012

Paper: CSIR-NET June 2012 · Subject: Inorganic Chemistry · Chapter: Inorganic Spectroscopy · Topic: Inorganic Spectroscopy – General · Marks: 2 · Difficulty: Medium

The total numbers of fine and hyperfine EPR lines expected for octahedral high-spin Mn(II) complexes are respectively ( $\mathrm{I}=5 / 2$ for Mn )

(a)3 and 30

(b)5 and 33

(c)5 and 30

(d)4 and 24

Answer

Answer: C ✓ checked by 4AB · confidence high

Explanation

S = 5/2 gives 2S = 5 fine-structure transitions; each is split by ⁵⁵Mn (I = 5/2) into 2I + 1 = 6 hyperfine lines: 30 in all.
