Relaxations of Excited States and Photo-Induced Structural Phase Transitions

This book covers the topics discussed during the 19th Thaniguchi Symposium. The phenomena within the scope of this conference are as follows: neutral-ionic transions of organic charge-transfer salts; optical excitations, lattice relaxations and photo-induced phenomena; optical properties of the C60 crystal and photo-induced polymerization; self-trapped excitons, polarons, solitons and other nonlinear photo-excitations in various insulators; photo-induced structural changes in ferroelectrics.
