The spectra were measured from pressed samples of the fibers using a SpectraScope accessory on a Thermo Scientific FT-IR spectrometer. The spectra were acquired at 2 cm^-1 digital resolution and then mathematically deresolved when converted to Thermo Scientific Omnic library format.

The spectra are listed in this document in alphabetical order by compound name. The index number of each spectrum appears to the left of the name. The generic name for the fiber, the manufacturer's name, the manufacturer's trade name, the fiber identification number assigned by CTS, the diameter and appearance of the fiber, and the manufacture code of the fiber are available on-line.

Thermo Scientific acknowledges the cooperation of Dr. Jay A. Siegel and his co-workers in the School of Criminal Justice at Michigan State University, who obtained the sample spectra.
