Some courses touch UV–Vis lightly: more conjugation generally shifts absorption to longer wavelengths. Useful as a supporting clue in conjugated systems.
What it does: Some courses touch UV–Vis lightly: more conjugation generally shifts absorption to longer wavelengths. Useful as a supporting clue in conjugated systems.
Typical reagents: UV-Vis (analysis; conjugation vs λmax)
Key intermediate: Varies / context-dependent
Driving force: Formation of more stable bonds / products
