Abstract

FT-IR photoacoustic spectroscopy (PAS) is discussed as a nondestructive method to probe the molecular composition of materials versus depth on the basis of the analysis of layers of experimentally controllable thickness, which are measured from the sample surface to depths of some tens of micrometers, depending on optical and thermal properties. Computational methods are described to process photoacoustic amplitude and phase spectra for both semi-quantitative and quantitative depth analyses. These methods are demonstrated on layered and gradient samples.

Near-surface analysis and depth profiling by FT-IR photoacoustic spectroscopy

Journal Article Yang, C; Bresee, R; Fateley, W - Appl. Spectrosc.; (United States)

Fourier transform photoacoustic spectroscopy (FT-IR/PAS) has proven to be a powerful technique for the near-surface characterization of solid materials. The effective sampling depth of FT-IR/PAS can be varied by using different interferometer mirror velocities, so that nondestructive depth profiling can be performed. In this research, sized cotton yarns, treated glass fibers, chemically modified poly(ethylene terephthalate) fibers and a naturally weathered poly(vinyl chloride) composite were investigated with the use of FT-IR/PAS at different mirror velocities. Penetration of the chemical additives in these materials was studied. It was demonstrated that FT-IR/PAS has the ability to investigate the changes in chemical nature withinmore »« less

Quantitative depth profiling of layered samples using phase-modulation FT-IR photoacoustic spectroscopy

Journal Article Jones, R; McClelland, J - Applied Spectroscopy

In phase-modulation FT-IR spectroscopy, all wavelengths in a spectrum are modulated at the same frequency and in phase. This factor makes the use of photoacoustic phase data for depth profiling samples much easier in phase modulation than in rapid scan. A method to quantitatively measure layer thickness by using the phase of a substrate spectrum peak is demonstrated with a series of samples consisting of thin polymer films on substrates. Additions to the basic method are demonstrated that extend its application to cases where the substrate peak is overlapped by a spectrum peak of the surface film. A linear relationshipmore »« less

Observation of FT-IR/photoacoustic and FT-IR/photoacoustic reflection-absorption spectra of Langmuir-Blodgett films on a metal substrate

Journal Article Ochiai, S; McClelland, J; Kobayashi, K; ... - Applied Spectroscopy; (United States)

Fourier transform infrared photoacoustic (FT-IR/PA) spectroscopy combined with the reflection-absorption (RA) technique is demonstrated for Langmuir-Blodgett (LB) films deposited on metal substrate FT-IR/PA and FT-IR/PA/RA spectra can be taken on the same LB film. By the use of FT-IR/PA and FT-IR/PA/RA methods. Spectra corresponding to transmission and RA spectra can bee identified for the same LB film on a metal substrate. The molecular orientation of the LB film can be analyzed with the use of these spectra.

Depth profile study of large-sized coal samples by Fourier transform infrared photoacoustic spectroscopy

Journal Article Zerlia, T - Appl. Spectrosc.; (United States)

A multidisciplinary approach is demonstrated to elucidate coal weathering at a molecular level. Fourier Transform Infrared Photoacoustic Spectroscopy (FT-IR/PAS) provides a technique for a compositional depth profile of coal by simply varying the modulation frequency (mirror velocity) of the light impinging upon the solid surface. In order that the potential of this technique in this field could be evaluated, large-sized coal samples were examined. The PA difference spectra obtained from the spectra taken at different modulation frequencies (i.e., different depths), on a sample aged in air, demonstrate the appearance of negative features in the CH infrared absorption which are indicativemore »« less

The use of step scan FT-IR/PAS for the study of structural changes in coal and char particles during gasification

Journal Article Yamada, Osamu; Yasuda, Hajime; Soneda, Yashushi - Preprints of Papers, American Chemical Society, Division of Fuel Chemistry

To understand the reactions occur during coal gasification, it is essential to investigate reactivity and structural changes in coal and char. As coal and char are solid which hardly dissolve into most of solvents, variety of applicable methods for analyses is limited. An FT-IR spectroscopy is a promising method to detect the status of various kinds of functional groups and their chemical and physical changes. Recently, FT-IR photoacoustic spectroscopy (FT-IR/PAS) of coal has been intensively studied. Depth profiling analyses using FT-IR/PAS is also discussed focusing on the technique to avoid a saturation of the photoacoustic signal. In this paper, amore »« less
