What is ultraviolet-visible absorption?

Q: What is ultraviolet-visible absorption?


A: Ultraviolet-visible absorption is a process where a molecule absorbs ultraviolet or visible light that excites electrons and causes an electronic transition from a ground state to an excited state.

Q: How is ultraviolet-visible absorption used in spectroscopy?


A: It is used in a technique of absorption spectroscopy known as ultraviolet-visible spectroscopy.

Q: What causes the electronic transition in ultraviolet-visible absorption?


A: The energy from the absorbed light causes the electronic transition from a ground state to an excited state.

Q: What happens to the electrons in ultraviolet-visible absorption?


A: The electrons become high energy due to the absorption of ultraviolet or visible light.

Q: Is ultraviolet-visible absorption a common phenomenon?


A: Yes, ultraviolet-visible absorption is a common phenomenon.

Q: What is the main principle of ultraviolet-visible spectroscopy?


A: The main principle of ultraviolet-visible spectroscopy is to measure the absorption of ultraviolet or visible light by a sample containing the molecule of interest.

Q: What is the significance of ultraviolet-visible spectroscopy in science?


A: Ultraviolet-visible spectroscopy is a widely used analytical technique in chemical, biological, and environmental analysis for determining the presence, quantity, and purity of a substance.
