UV-visible spectroscopy involves what type of phenomenon?
A) Binding of chemical bonds
B) Electron transitions between orbitals
C) Molecular rotations
D) Nuclear spin transitions
E) Stretching of chemical bonds

Question

Quizplus · Accepted Answer

UV-visible spectroscopy involves electron transitions between orbitals. When a sample is exposed to UV or visible light, some of the electrons within the sample's molecules may be promoted to higher energy levels. When these electrons relax back down to their original energy levels, they emit radiation at a particular wavelength, which can be measured to provide information about the sample's chemical structure.
