CYMSQ2 marksNeeds review
The UV-visible spectrum of [Ni(en)₃]²⁺ (en = ethylenediamine) shows absorbance maxima at 1120 cm⁻¹, 1830 cm⁻¹, and 2900 cm⁻¹.
Absorbance maximum
Electronic transition
(a) 1120 cm⁻¹
(i) ³A₂g → ³T₁g (F)
(b) 1830 cm⁻¹
(ii) ³A₂g → ³T₂g
(c) 2900 cm⁻¹
(iii) ³A₂g → ³T₁g (P)
[Given: Atomic number of Ni = 28]
The correct match(es) between absorbance maximum and electronic transition is/are
