Q: What is the primary interaction of UV-Vis spectroscopy with a sample?
Solution:
UV-Vis spectroscopy primarily involves the absorption of light by molecules, which promotes electrons to higher energy levels.
Steps: 5
Show Steps
Step 1: Understand that UV-Vis spectroscopy is a technique that uses light.
Step 2: Know that the light used is in the ultraviolet (UV) and visible (Vis) range.
Step 3: Recognize that when light hits a sample, some of it can be absorbed by the molecules in the sample.
Step 4: Learn that when molecules absorb this light, it gives energy to their electrons.
Step 5: Understand that this energy allows the electrons to move to higher energy levels within the molecule.
