UV radiation and Electronic Excitations. The difference in energy between molecular bonding, non-bonding and anti-bonding orbitals ranges from 125-650 kJ/mole. This energy corresponds to EM radiation in the ultraviolet (UV) region, 100-350 nm, and visible (VIS) regions 350-700 nm of the spectrum. Spectroscopy . . Is the interaction between matter and electromagnetic radiation (light). . Spectroscopy is commonly used in chemistry to detect, identify, and quantify information about different atoms and molecules. 1 IR-Spectroscopy IR region The part of electromagnetic radiation between the visible and microwave regions 0.8  m to 50  m ( 12,500 cm -1 - 200 cm -1 ) is called IR region Most interested region in Infrared Spectroscopy is between 2.5 Piet Van Duppen.

X-ray Photoelectron Spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is used to determine quantitative atomic composition and chemistry.. Spectroscopy & Structure. All spectroscopic techniques are used in two ways:. To prove that two compounds are identical. A compound’s spectra are unique to that compound. To help establish the structure of a new compound. (. XRD. ). . X. -. R. ay . P. hotoelectron . S. pectroscopy. (. XPS. ). By:. . Roya. . Ayazi. . Nasrabadi. What is X. -. ray. ?.
