What is the principal difference between UV and IR spectroscopy?
What is the principal difference between UV and IR spectroscopy?
IR is a lower energy radiation and is generally close in energy to many vibrational transitions of molecules (ie: affects proton displacement). UV/VIS is much higher energy, and closer to the electronic transitions of molecular orbitals (ie: affects electronic structure/electrons in orbitals).
What is the principle of UV and IR?
The Principle of UV-Visible Spectroscopy is based on the absorption of ultraviolet light or visible light by chemical compounds, which results in the production of distinct spectra. Spectroscopy is based on the interaction between light and matter.
What is the principle of IR spectroscopy?
Principle of Infrared Spectroscopy: IR spectroscopy works on the principle that molecules absorb specific frequencies that are characteristic of their structure. At temperatures above absolute zero, all the atoms in molecules are in continuous vibration with respect to each other.
