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

In recent years, particular attention has been devoted to developing "soft" chemistry approaches towards the synthesis of new lanthanide (rare-earth) materials under ambient conditions. This book presents a simple hydrothermal synthetic approach to produce a number of new erbium-based materials in the form of crystalline microflowers, hexagonal microlayers, microsticks and microspheres, which are comprised of nanoparticles, as well as nanofibers, nanorods and nanolayers. This book also discusses recent results concerning the synthesis, phases changes and vibrational spectra of rare-earth orthophosphates, together with similar data for the diphosphate, ErKP2O7.2H2O, and the tricyclophosphate, ErNa3(P3O9)2.9H2O.
