A wide variety of radiation sources are employed in order to cover the electromagnetic spectrum. Sodium filters the alien star light of HD 209458 as the hot Jupiter planet passes in front.

Receive articles like this one, product launches, press releases and more with our quarterly newsletter focusing on either Physical Science or Life Science. This can be done if the absorption coefficient (ε) is known and Beer's law is obeyed.In practice, we do not generally rely on published values of ε because this quantity may be very sensitive to idiosyncrasies of reagent preparation and instrument design. Increasing the temperature or pressure of the absorbing material will also tend to increase the line width.

This produces an evanescent wave at the reflecting surface. as here in equation (3): A = -log10(IT/Io) = -εdc where:IT is the monochromatic radiant power transmitted by the absorbing mediumIo is the monochromatic radiant power incident on the medium τi is the internal transmittance (=IT/Io)ε is the molar (decadic) absorption coefficient c is the amount concentration d is the absorption path length A is the (decadic) absorbance Internal transmittance τi, i.e. The progress of a chemical reaction can be followed using a spectrophotometer to measure the concentration of either a reactant or a product over time. An excited molecule can possess any one of a set of discrete amounts (quanta) of energy described by the laws of quantum mechanics. Rotational lines, for instance, occur when the rotational state of a molecule is changed.

Crouch, Spectrochemical Analysis, Prentice Hall, 1988, ISBN 0-13-826876-2 ^ "Gaseous Pollutants Fourier Transform Infrared Spectroscopy". At each grain the photons encounter, a certain percentage are absorbed. The IRS technique is non-destructive and can be used for solids, liquids, and powders.For thin films, the IRS spectra are the same as transmission spectra.
