The electronic transition that is involved in the visible region is:
Correct answer: B. d - d
- A. σ - σ
- B. d - d
- C. π - π
- D. π - σ
Explanation
d-d transitions are electronic transitions that occur between the molecular orbitals that are mostly metallic in character; specifically between the d-orbitals of a transition metal complex. When electronic transitions occur between these orbitals, the color observed is complementary to the wavelengths absorbed in the visible region.

About Spectroscopy and Analysis
Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
