Infrared Library Search on Principal-Component-Analyzed Fourier-Transformed Absorption Spectra

Not Accessible

Your library or personal account may give you access

Abstract

Fourier-transformed infrared absorption spectra are compressed by principal-component analysis. Searches using the compressed data demonstrate the success of the compression. A search technique utilizing principal components in a prefilter selection produces the most efficient infrared library search method.
