Method: Absorption

Absorption spectroscopy provides information on a sample by determining the attenuation of radiation due to interaction with the sample. X-ray excitation results in the emission of photoelectrons and photons (fluorescence) revealing details of the chemical, electronic, and molecular structure of materials close to the surface (depth depends on photon energy of incident light and photoelectron energy).
IR absorption results in vibrational excitation and can be used for instance to study the structural and functional interactions of proteins.
