Infrared spectroscopy studies the interaction of infrared radiation with matter. Molecules absorb the infrared radiation at frequencies that are characteristic of their structure. An infrared spectrum is a dependence of intensity of the absorbed or transmitted radiation on its frequency or wavelength. Information on the position and relative intensity of the bands in the infrared spectrum is used for making conclusions about structure of the matter under study.

Infrared spectra are recorded on infrared spectrometers. The Spectrum 100 Fourier Transform Infrared Spectrometer (Perkin-Elmer, Inc.) is a bench-top instrument giving fast data collection over a total range of 4000 to 600 cm-1 with a best spectral resolution of 0.5 cm-1. The following sampling accessories are included:

  • Universal Attenuated Total Reflectance (ATR) Sampling Accessory for measuring spectra of powders, pastes, gels and liquids; the technique is very efficient; samples are analyzed as they are.
  • Diffuse Reflectance Sampling Accessory for collecting spectra from samples of powders, fine particles and highly scattering materials not suitable for transmittance measurements.
  • Sample Shuttle Accessory for transmittance IR measurements.

The spectrometer is located in room LS 1091.
