FT-Guys is the test nickname of the analytical chemistry research group headed by Dr. Peter Griffiths. "FT" stands for Fourier Transform: a mathematical operation invented by Frenchman Jean Fourier (1768-1830) which converts any periodic function, regardless of its complexity, into a sum of basic sine and cosine waves. "Guys" stands for…well, we’re a bunch of guys (this includes both men and women).

The FT, with the use of modern computers, has become a mainstay in analytical chemistry for interpretation of chemical spectra. The FT-Guys research laboratory concentrates on the invention, improvement, and expanded utilization of the FT operation for vibrational spectroscopy (infrared and Raman). This includes, but is not limited to, such applications as infrared spectroelectrochemistry, open path FT-IR, ultra-rapid scanning FT-IR, step scan FT-IR, FT-Raman spectroscopy, GC/FT-IR, HPLC/FT-IR, SEIRA, and SERS.

For full definitions and information on these techniques see our spectroscopy links.

Our logo is based on our location at the University of Idaho in Moscow (pronounced "moss-co"), Idaho. No, we do not grow potatoes, but we have probably looked at them in the IR at some point in time. The red squiggly line in our logo is an interferogram: the generic resulting signal from a Michelson interferometer prior to conversion by FT.
