25. In analytical spectroscopy, different regions of the electromagnetic spectrum interact with matter by inducing specific quantum transitions. Which of the following pairs correctly matches the spectral region with its corresponding quantum transition and reflects the correct energy relationship? (A) X-ray: transitions of valence electrons; higher energy than UV radiation. (B) Ultraviolet-Visible (UV-Vis): transitions of inner-shell electrons; lower energy than Infrared radiation. (C) Infrared (IR): changes in the configuration of nuclear spins; used for functional group identification. (D) Microwave: transitions between rotational energy levels of molecules; longer wavelength than Infrared radiation. (E) Radio wave: vibrational transitions within a molecule; used in Nuclear Magnetic Resonance (NMR) spectroscopy.
