transitions Absorption of UVvisible radiation by a molecule

transitions. Absorption of UV-visible radiation by a molecule results in a) Rotational b) Stereochemical c) Electronic d) Vibrational 1,

Solution

Rotational spectroscopy refers to the Absorption spectroscopy when microwave region of the electromagnetic radiation is absorbed by the molecule.

Electronic spectroscopy means the absorption of ultraviolet visible region of the radiation and underugo the excitation of electronic energy levels of a molecule. So answer is C

Vibrational spectroscopy refers to the absorption spectroscopy which happens due to the excitation of vibrational levels of a molecule.

Finally, fluorescence spectroscopy is complementary to the uv visible spectroscopy which refers to the emission spectroscopy of deexcitation of electronic levels.
