TL;DR: A review of analytical applications of matrix isolation Fourier transform infrared spectroscopy is presented in this paper, along with practical techniques for obtaining analytically useful results, and a few studies relating to matrix isolation used in conjunction with Raman and conventional IR Spectroscopy are reviewed.
Abstract: A review of analytical applications of matrix isolation Fourier transform infrared spectroscopy is presented. The characteristics of matrix isolation spectroscopy are discussed along with practical techniques for obtaining analytically useful results. A few studies relating to matrix isolation used in conjunction with Raman and conventional IR spectroscopy are reviewed. The majority of analytical applications of matrix isolation vibrational spectroscopy has entailed the use of FT-IR techniques. Qualitative and quantitative results from a number of sample types are presented. The coupling of matrix isolation vibrational spectroscopy with chromatographic separations is reviewed.

TL;DR: In this article, it was shown that the empirical correlation between the infrared (IR) stretching frequency of the Si-H bond in substituted silane molecules (SiH3R1, SiH2R1R2, and SiHR 1R2R3 with Ri the substituted molecular fragment) can be understood on a fundamental basis as the dependence of frequency on the bond order (S component) of the bond.

TL;DR: The far infrared reflection spectra of amorphous AsxSe1-x systems (0≤x≤0.5) were measured in the wavenumber range 30-500 cm-1 at room temperature, and one-mode type behaviors of the dominant modes were observed.
Abstract: The far infrared reflection spectra of amorphous AsxSe1-x systems (0≤x≤0.5) were measured in the wavenumber range 30–500 cm-1 at room temperature, and one-mode type behaviors of the dominant modes were observed. The optical constants were calculated by Kramers-Kronig analysis, and were also analyzed by the classical oscillator models. The effective charges of the AsSe3 pyramidal units were calculated. The dependence of the infrared dominant modes on the As concentrations show that hetero-bondings and therefore pyramidal units are predominant in this system, and slight modifications of the molecular models are necessary to explain the experimental data.

TL;DR: In this article, a brief theoretical review of IR emission spectroscopy of a heterogeneous catalytic system in reaction conditions is given, and experimental problems especially related to the microreactor designed for in situ IR emission investigations of catalytic reactions are discussed.
Abstract: Infrared spectroscopic aspects of IR emission investigations of a heterogeneous catalytic system in reaction conditions are outlined. A brief theoretical review of emission spectroscopy is given. In addition, experimental problems especially related to the microreactor designed for in situ IR emission investigations of catalytic reactions are discussed. It can be concluded that most experimental problems are not prohibitive. Infrared emission spectroscopy turns out to be a feasible technique over both a wide frequency range and a large temperature range. This is illustrated by a few experimental results.

TL;DR: In this paper, the υ5 band of methylacetylene has been studied simultaneously by means of CO2 Laser Stark spectroscopy and high resolution infrared absorption spectrographs (0.012 cm−1).
Abstract: The υ5 band of methylacetylene has been studied simultaneously by means of CO2 Laser Stark spectroscopy and high resolution infrared absorption spectroscopy (0.012 cm−1). The primary aim of this work was to assign all the Stark coincidences. Effective vibration-rotation parameters and the dipole moment of the v5=1 state have been determined.

TL;DR: In this article, the effects of isochronal annealing on the infrared and far-infrared spectra of very heavily B- and P-dopeda-Si(H) are reported.
Abstract: The effects of isochronal annealing on the infrared and far-infrared spectra of very heavily B- and P-dopeda-Si(H) are reported. Upon annealing, the B-H stretching mode evolves into two bands centered at 2475 and 2370cm−1. The broad band of the heavily B-doped samples between 600 and 900cm-1 is resolved into three peaks or absorption shoulders located at 830, 725, and 630cm-1. The 640cm-1 band of the heavily P-doped samples splits into two peaks centered at 630 and 670cm-1. The assignment of the above peaks is discussed. The intrinsic infrared absorption due to the Si lattice modes changes only little as a result of the annealing. These changes are a measure of the H-induced ir activity of the Si-Si bands.
