Subject: Inorganic Chemistry · Chapter: Inorganic Spectroscopy · Topic: Inorganic Spectroscopy – General · Exam: CSIR-NET JUNE 2011 · Marks: 2 · Difficulty: Medium
In the EPR spectrum of tetragonal Cu(II) complex, when $g_{\parallel} > g_{\perp} > g_{e}$, the unpaired electron resides in the orbital.
(a)$\mathrm{d}_{xy}$
(b)$\mathrm{d}_{x^{2}-y^{2}}$
(c)$\mathrm{d}_{z^{2}}$
(d)$\mathrm{d}_{xz}$
Answer
Answer (as printed): B
Explanation
Gives the evidence that $\mathrm{Cu^{2+}}$ ion is present in a tetragonally distorted octahedral field; the unpaired electron resides in the $d_{x^2-y^2}$ orbital.
