The book describes basic techniques of Fourier-Transform Infrared (FTIR) and Raman scattering spectroscopies. The textbook is complemented by an extensive set of experiments which can be conducted by broadly available as well as advanced instrumentation. After discussion of prsent theoretical approaches, instrumentation, data handling that explain the phenomenon of vibrational spectroscopy, the book reports new and exciting experiments and applications of the many fascinating spectroscopic effects. The manual is designed for students of chemistry, environmental protection, biophysics, medical and life sciences universities. Undoubtedly it will be also helpful in analytical laboratories.
