Factor Analysis Applied to Fourier Transform Infrared Spectra

Volume 33, Number 4 (Aug. 1979) Page 351-357

Antoon, Mitchell K.; D'Esposito, Louis; Koenig, Jack L.


The feasibility of applying the methods of factor analysis to Fourier transform infrared spectra is examined. The method is designed to determine the number of components contributing to a spectral region. The technique has been applied to a model system consisting of solutions of p-, o-, and m-xylenes. The method has also been used for calculating the number of independently absorbing species in several polymer systems. Spectral requirements and the general applicability of factor analysis are also discussed.
