Infrared Absorption Spectra

The author examines current applications of infrared spectroscopy in forensic practice and in various areas of science and technology. The paper includes an overview of objects that warrant the use of this forensic analytical technique. It is pointed out that not all capabilities of the method are currently put to use by forensic practitioners. It is also noted that methods based on infrared spectroscopy can be used for quantitative analysis, as well as the study of far and near infrared absorption spectra for forensic purposes.

Abstract A technique to obtain infrared absorption spectra of orientated molecules, dissolved in a liquid crystal, which is placed in a strong magnetic field, is described. The degree of orienta­tion of 4,4'-dihexoxyazoxybenzene is measured at various temperatures. The maximum degree of orientation of 4-bromo-benzonitrile and 4-cyanobenzoic acid is measured in a 10% solution in 4,4'-dihexoxyazoxybenzene to be 0.35 and 0.55, respectively.

Abstract The infrared absorption spectra of typical prostatic, dental, and salivary gland calculi are presented. Similarly, the spectrum given by typical biliary tract calculi is demonstrated. Examples of the extension of this method of identification to common toxicologic problems are shown. The advantages of the potassium-bromide presseddisk preparation for analyses of these substances in the solid state are indicated and discussed.

The solution of the problem of identification of amber (succinite) on the example of natural polymer material of organic origin on the basis of its infrared absorption spectra is proposed. Taking into account the growing demand for the use of such composite materials on an industrial scale and the insufficiency of existing methods for determining their composition, the proposed method can become a new solution to the problem of identification. The basis of the proposed method for the study of succinite using infrared spectroscopy is translucent spectroscopy, with the measurement of mirror and diffuse reflection. The samples amber of the Palmniken Deposit obtained in the city of Kaliningrad of the Russian Federation were used as the objects studied. The data of infrared spectra of succinite obtained by the proposed method of infrared spectroscopy are obtained and presented in comparison. Five main links on the obtained infrared spectra have been experimentally determined, which can be used as characteristic features for identification and diagnostics of succinite by the material composition. The proposed method may be of interest in the theory of knowledge of material science, research related to the processes of identification, processing of production of amber.
