Real Diatomic Molecules Temperature Spectrum of Nitrogen Isotopic Substitution Nuclear Spin Statistics Predict the Spectrum of Oxygen This experiment is based around interaction with a computer simulation of a Raman spectrum. The model is embedded into the web pages that contain the practical. Spectroscopy is the study of the exchange of energy between radiation and matter. Light of a known frequency irradiates a sample. Molecules in the sample emit or absorb distinct packets of energy. The frequency and intensity of light hitting a detector is converted by a spectrometer into a spectrum. In the lab often it is not energy that is measured directly but frequency of the electromagnetic radiation. It is simple to convert frequency into energy units using the equation: (1) << previous page www.physchem.ox.ac.uk next page >>
