In infrared spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). The resulting spectrum represents the molecular Fourier Transform Infrared Spectroscopy (FTIR) has been used to characterize inductively coupled CF4 plasmas in a GEC Reference Cell in-situ In examining these FTIR spectra, several assumptions spectrum from an ‘‘unknown’’ with previously recorded reference spectra. This is the basis of computer-based spectral searching. In the absence of a suitable reference database, it is possible to effect a basic interpretation of the spectrum from first principles, leading to characterization, Fingerprint analysis of FTIR spectra of polymers containing vinyl acetate• Aurelio Ramírez-Hernández, Celia Aguilar-Flores & Alejandro Aparicio-Saguilán Universidad del Papaloapan, San Juan Bautista Tuxtepec Oax.
