Course objectives
The course represents an introduction to infrared spectroscopy - the basic principles of interaction of IR radiation with matter, the formation of the IR spectrum. A major part of the subject deals with practical use and processing of measured IR spectra in order to extract important crystallochemical parameters of the given substance, which can be used ie. to refine the spatial orientation or concentration of the absorbing species. Practical exercises consist mainly of spectral processing using the Peakfit (Jandel Scientific) software and final evaluation of the results. Most spectra used will be absorption bandgroups due to the presence of hydrogen in nominally anhydrous minerals. The successful candidate will be capable of processing and evaluating an IR spectrum - stating the apparent cause of the absorptions, the concentration and orientation of the absorber. Practical use of this knowledge features mainly the characterisation of hydrogen content in minerals, which cannot be measured ie. by means of an electron microprobe. Furthermore, the successful candidate will be capable of understanding and critically revising the results of other authors in the frame of papers dealing with IR spectroscopy.
Syllabus
  • IR radiation as an electromagnetic wave - electric and magnetic component.
  • Relations between units describing the energy of electromagnetic waves and their conversions - wavenumber, wavelength, frequency, energy
  • Interaction of IR radiation with matter - types of movement of structural components, consequent absorption of IR radiation and its quantification.
  • Measurements using polarized IR radiation - spatial orientation of the absorber within the examined crystal.
  • Concentration of the absorber in the sample.
  • Practical examples of IR spectra of nominally anhydrous minerals - problems with background, sample contamination, artefacts, etc., measurement at low temperatures...
  • Significance of IR spectroscopic investigations for geosciences
  • Introduction to the program Peakfit, fitting of spectra of nominally anhydrous minerals, refinement of important structural parameters.
