ABSTRACT
Vibrational spectroscopy provides detailed information on both structure and dynamics of molecular species. Infrared (IR) and Raman spectroscopy are the most commonly used methods, and will be covered in detail in this chapter. There exist other methods to obtain vibrational spectra, but those are somewhat more specialized and used less often. They are discussed in other chapters, and include: inelastic neutron scattering (INS), helium atom scattering, electron energy loss spectroscopy (EELS), photoelectron spectroscopy, among others.
