Improve your ability to identify molecules using infrared spectrometry. This course is appropriate for technicians who seek to improve their skills and advance their careers, and for managers whose labs have an FTIR and who need to understand what information the device yields so they can manage their labs more intelligently.
* A systematic, 10-step approach to interpreting IR spectra successfully
* How molecules absorb infrared radiation
* What peak positions, heights, and widths mean
* Four ways to make interpreting mixture spectra easier
* The right way to perform spectral comparisons (identities)
* The diagnostic infrared bands of economically important molecules
* How to integrate peak position, intensity, and width information to attack unknown and mixture spectra
* Special discussion of polymer and inorganic spectra
* How library searching makes spectral interpretation faster and easier
* Important infrared bands of a wide variety of economically important molecules, including polymers and inorganics
Session titles
Day 1
* The Fundamentals of Infrared Interpretation — The properties of light; how molecules absorb infrared radiation; the meaning of peak positions, heights, and widths; a systematic approach to spectral interpretation.
* Functional Group Analysis of Hydrocarbons — Alkanes: C-H stretching and bending vibrations; alkenes: distinguishing isomers; alkynes; aromatic hydrocarbons.
* Functional Groups Containing the C-O Bond — Overview: the C-O stretch; alcohols & phenols; ethers; the methoxy group.
Day 2
* The Carbonyl (C=O) Functional Group — The C=O stretch; ketones; aldehydes; carboxylic acids and derivatives; esters: the “Rule of 3.”
* Organic Nitrogen Compounds — Amides; amines; CH3 groups attached to nitrogen; nitriles: the CºN bond; nitro compounds.
* Infrared Spectra of Polymers — Low and high density polyethylene; polypropylene; polystyrene; polyethylene terephthalate (PET); nylons.
* Inorganics — Overview; sulfates; silica; inorganic carbonates; nitrates and phosphates.
* Interpretation Aids — Spectral subtraction: simplifying mixture spectra; library searching.
