High-pressure Molecular Spectroscopy describes examples of the applications of several spectroscopic methods to investigate the behavior of various chemical systems under high pressures, including guest-host interactions, chemical reactions, molecule-based multiferroics, lanthanide ion-doped glasses, and organic, inorganic and organometallic materials. The techniques involved include:

• Luminescence studies
• Inelastic neutron scattering
• Infrared and Raman studies
• Synchrotron X-ray diffraction
