Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Infrared spectroscopy is a method that analyzes the vibrations of atoms in a molecule. An infrared spectrum is generally acquired by sending infrared light through a sample and calculating how much of the incident radiation is absorbed at each energy level. The frequency of vibration of a section of a sample molecule resembles the energy at absorption. The fundamental concepts and terminology of infrared spectroscopy are presented in this chapter. The vibrations of molecules will be examined in this section since they are critical to the understanding of infrared spectra. Various applications of IR spectroscopy are also discussed in brief.
