Spectroscopy involves an interaction between matter and light . (EMR). Light can be thought of as waves of energy or packets (particles) of energy called photons. Properties of light waves include wavelength and frequency. 2. 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.
