Infrared Spectroscopy (FT-IR)
Thermo Nicolet Avatar 380 FT-IR
This is a research-grade FT-IR, with cesium iodide optics that can be operated at high resolution (up to 0.4 cm-1). The cesium iodide optics allows the instrument to observe from 200-4000 cm-1. The extended range permits analysis of metal-ligand bonds for inorganic materials. Liquids samples can be run on salt plates, while solid samples have the option of being pressed into KBr or CsI pellets.
This versatile instrument is used in a variety of applications in the chemistry undergraduate labs, ranging from identification of functional groups in organic and inorganic chemistry labs to observation of rotational states of gasses. The laboratory courses that use the FTIR include Chem 263/263A/264/264A, Chem 423, Chem 443 and Chem 481.
