Analytical Chemistry, 1982
This review covers the literature for the two year period from late 1983 to late 1985 on aspects of Infrared Spectrometry which are relevant to chemical analysis. It is intended to review the state of the art in analytical infrared spectrometry as portrayed by the recent literature. (This review covers mainly vibrational spectra.

Aerosol spectrometry in the infrared
Applied Optics, 1980Aerosol spectrometry denotes a methodology for describing spectral effects of atmospheric constituents in quantitative, standardized, basic terms. It is based on the premise that most atmospheric constituents can be described (albeit in some cases very unconventionally) as specialized kinds of aerosols, some of which exhibit complex changes in spectral

A Reflecting Microscope for Infrared Spectrometry*
Journal of the Optical Society of America, 1952A reflecting microscope designed for use in front of the entrance slit of a Perkin-Elmer single-beam infrared spectrometer is described. It is shown that the heating effect of the condensed beam on the sample is not significant except in the case of compounds which absorb strongly in the 3-micron region of the spectrum, and then only if the sample is ...

Validation procedures in near-infrared spectrometry
Analytica Chimica Acta, 1994Abstract Three validation procedure, single evaluation set, cross-validation and repeated evaluation set, were tested on near-infrared spectrometric data to evaluate the predictive residual standard deviation and the complexity of the regression model based on partial least-squares (PLS) regression.

Hydration of lysozyme as observed by infrared spectrometry
Biopolymers, 2005AbstractInfrared spectra of a film of lysozyme 3 μm thick, immersed in an atmosphere displaying a relative humidity, or hygrometry, which spans the whole range from 0 to 1 at room temperature, are recorded. The evolution of the spectra with this relative humidity is quantitatively analyzed on the basis of a newly proposed method.

Fourier Transform Infrared Spectrometry
Science, 1983The theory and instrumentation for Fourier transform infrared spectrometry are discussed. These instruments measure infrared spectra of the same quality as spectra measured on grating spectrometers in about one thousandth of the time. Their sensitivity advantage for spectra measured in equal times is between a factor of 10 and 100.

Differential Thermal Lens Spectrometry in the Infrared
Israel Journal of Chemistry, 1998AbstractThe operational principle and the first application of a novel infrared differential thermal lens spectrometer for optical studies of liquid samples is described. Compared to a conventional double‐beam (pump/probe) configuration, the instrumental setup described here offers the possibility to substantially reduce (as much as 30 times) the ...

Identification of Paper by Infrared Spectrometry
Spectroscopy Letters, 1982Abstract The possibilities offered by IR spectrometry for the characterization of paper samples were explored. Two aspects were considered : the content of inorganic matter and some of its structural features.

Biological applications of infrared spectrometry
Fresenius' Zeitschrift für analytische Chemie, 1986A brief overview of infrared studies of biological systems is presented. Relevant studies of the four classes of biomolecules, the proteins, the lipids, the carbohydrates and the nucleic acids are exemplified with results from the recent literature. The great potential of infrared spectrometry for biological studies is demonstrated.

Linked gas chromatography-infrared-mass spectrometry
Analytical Chemistry, 1987For almost 20 years the idea of linking a gas chromatograph with both an infrared and a mass spectrometer to form an integrated analysis system (GC/IR/MS) has intrigued analytical chemists. For example, in one of the earliest GC/IR papers, which reported GC/IR spectra of 10-18 wavenumber resolution with microgram-level sensitivity, Low and Freeman ...
