I. INTRODUCTION In recent years the different branches of analytical chemistry, especially those dealing with the identification of individual molecules, as well as qualitative and quantitative analysis of molecular mixtures, have become increasingly important. Questions in these areas often arise in solving a number of global problems. For example, the analysis of compounds produced in chemical reactions under ordinary conditions is common, and more work is being done under conditions of plasma, photochemistry under different interaction energies, laser synthesis, and so on. The analysis of molecules and molecular associates is also encountered with regard to environmental pollution: organic impurities in water, the state of the atmosphere, the state of biological objects, and many others. It should be remembered that molecules in natural media enter into various reactions and change with time, thus forming innumerable derivatives. Moreover, a problem for a number of industries is automatic protection of... |
