What type of transition is primarily observed in UV-Vis spectroscopy?

Step 1: Understand what UV-Vis spectroscopy is. It is a technique used to measure the absorption of ultraviolet and visible light by a substance.
Step 2: Know that light has energy, and different types of light have different energy levels.
Step 3: Learn that in UV-Vis spectroscopy, we are interested in how light interacts with electrons in a substance.
Step 4: Recognize that electrons in atoms or molecules can exist at different energy levels.
Step 5: Identify that when UV or visible light hits a substance, it can provide enough energy for electrons to move from a lower energy level to a higher energy level.
Step 6: Conclude that these movements of electrons between energy levels are called electronic transitions, which are the primary focus of UV-Vis spectroscopy.
