UV Spectroscopy. Introduction. 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. Fall . 2017. First Order Spectra.
