n of the peaks in the IR absorption spectra can be judged from the nature of the substance (qualitative analysis), and the intensity of the absorption bands - the number of substances (quantitative analysis). , IR spectroscopy is based on the fact that irradiation of a substance is non-monochromatic infrared exists because of the vibration and electronic degrees of freedom, that is due to the absorbed incident radiation, at frequencies corresponding to the energy that appears because of the difference of the vibration and electronic levels. In the transmission spectrum appear the features that allow to judge the characteristic frequencies of molecular vibrations and their electronic properties.characteristics (position of the maxima of bands and their half-width, intensity) depend on the masses of its constituent material atoms, the geometrical structure, the characteristics of interatomic forces, the charge distribution (Hamm, Lim, Hochstrasser, 1998). of Mass Spectrometry
Mac-spectrometry is one of the most effective methods for expressing the analysis and establishing a structure of individual organic, synthetic and natural compounds and their mixtures (Price & Phil 1991). Due to its extremely high sensitivity and the possibility of using in combination with gas and liquid chromatography, this method is widely used in organic, bioorganic, biological, physical, analytical, medical chemistry, the chemistry, pharmacology, toxicology, environmental protection, forensic and in control of production. One way to establish the structure of the investigated compounds by this method is automatically registered spectrum of the comparison spectra with the bank of spectra that are entered into the computer memory. Mass spectroscopy is a method based on the research of materials by determining the mass of ions of the substance (often related to their mass ion charge) and their quantities (Fenn, Mann, Meng, Wong, Whitehouse, 1989). The sequence of values ​​?? of the masses and their relative content (concentration) is called the mass spectrum. Mass spectroscopy uses a vacuum separation of ions of different masses under the influence of electric and magnetic fields. Therefore, the investigated substance, firstly, is subjected to the process of ionization (Price & Phil 1991). The process of ionization is excluded the study of ionic structure already ionized gases, such as electrical discharge in the ionosphere or planets. In the case of liquid and solid substances they are pre-evaporated and then ionized. Mostly the positive ions are researched, because the existing methods of ionization allow receiving them in a more direct way and in larger quantities than negative. However, in some cases tested and negative ions (Schwartz, Michael, Senko, John, Syka, 2002). The first mass spectra were obtained in the UK by JJ Thomson and F. Aston. They led to the discov...
