What is the primary interaction that occurs in UV-Vis spectroscopy?

Step 1: Understand that UV-Vis spectroscopy is a technique used to study how substances absorb ultraviolet and visible light.
Step 2: Know that light is made up of different energy levels, and each type of light has a specific energy.
Step 3: Realize that when light hits a substance, it can cause electrons in the substance to move.
Step 4: Identify that electrons can exist at different energy levels within an atom or molecule.
Step 5: Learn that UV-Vis spectroscopy primarily measures the transition of electrons from a lower energy level to a higher energy level when they absorb light.
