Infrared Spectroscopy Laboratory
The Infrared Spectroscopy Laboratory supports studies of the vibrational, or thermal infrared, properties of rocks (including meteorites) and minerals, using both emission and reflection measurement techniques. Our primary users are interested in understanding the variation in spectral characteristics of samples of differing mineralogies, chemistries, structures, particle sizes, shock levels, etc. The knowledge that is gained from these studies is applied to the analysis of infrared spectra of unknown samples, as well as remote sensing data collected over Earth and Mars.
The lab is equipped with a Nicolet 470 FTIR spectrometer with a CsI beamsplitter for coverage to 200 cm-1. The spectrometer is configured for both hemispherical reflectance and emission measurements. The hemispherical reflectance attachment (provided by Dr. Paul Lucey) covers the wavelength range from ~4000 - 600 cm-1 using a CsI beamsplitter and a liquid nitrogen-cooled MCT detector. The emission configuration is modeled after the configuration at the Thermal Emission Spectrometer (TES) laboratory at Arizona State University. We welcome opportunities to collaborate on projects with investigators from other institutions. Details of the laboratory and spectra are available from Dr. Victoria Hamilton. For more information on infrared spectroscopy (also referred to as vibrational spectroscopy) at HIGP contact Dr. Victoria Hamilton. Text and images courtesy V. Hamilton. |
