The main goal of this book is to give a systematic description of intramolecular quantum dynamics on the basis of only the symmetry principles. In this respect, the book has no analogs in the world literature. The obtained models lead to a simple, purely algebraic, scheme of calculation and are rigorous in the sense that their correctness is limited only to the correct choice of symmetry of the internal dynamics. The book is basically intended for scientists working in the field of molecular spectroscopy, quantum and structural chemistry.

The concept of adiabatic electronic potential-energy surfaces, defined by the BornOCoOppenheimer approximation, is fundamental to our thinking about chemical processes. Recent computational as well as experimental studies have produced ample evidence that the so-called conical intersections of electronic energy surfaces, predicted by von Neumann and Wigner in 1929, are the rule rather than the exception in polyatomic molecules. It is nowadays increasingly recognized that conical intersections play a key mechanistic role in chemical reaction dynamics. This volume provides an up-to-date overview of the multi-faceted research on the role of conical intersections in photochemistry and photobiology, including basic theoretical concepts, novel computational strategies as well as innovative experiments. The contents and discussions will be of value to advanced students and researchers in photochemistry, molecular spectroscopy and related areas.

Palliative care is a rapidly evolving field focused on the management of problems that undermine the quality of life of patients with progressive incurable medical disorders. It is fundamentally concerned with all factors- physical, psychological, social, and spiritual- that contribute to suffering, and prevent a death with comfort and dignity. Palliative care is a fundamental aspect to good clinical practice, the "parallel universe" to therapies directed at cure or prolongation of life. All clinicians who treat patients with chronic life-threatening diseases are engaged in providing palliative care, continually attempting to manage complex symptomatology and functional disturbances. The scholarly foundation of palliative care is advancing, and resources are needed to highlight the findings of empirical research. TOPICS IN PALLIATIVE CARE has been designed to meet the need for enhanced communication in this field. To highlight the diversity of concerns in palliative care, each volume of the TOPICS IN PALLIATIVE CARE Series is divided into sections that address a range of salient issues: symptom control, psychosocial functioning, spiritual or existential concerns, and ethics. The authors present and evaluate existing data, provide a context drawn from both the clinical and research settings, and integrate knowledge in a manner that is both practical and readable. The specific topics in this volume are: Pediatric Palliative Care, Management of Bone Pain, Psychopathology in Patients with Cancer, and Skin Disorders and their Management.

The Fifteenth Jerusalem Symposium reflected the high standards of the former international scientific meetings, which convene once a year at the Israel Academy of Sciences and Humanities in Jerusalem to discuss a specific topic in the broad area of quantum chemistry and biochemistry. The topic at this year's Jerusalem Symposium was intramo lecular dynamics, a subject of central interest for theoreticians, che mists and biologists. During the last two decades, there has been remarkable pro gress in our understanding of time dependent phenomena. The development and application of the modern techniques of quantum mechanics and sta tistical mechanics to excited-state dynamics and to chemical and biophy sical systems constitutes a fast developing current research area. The main theme of the Symposium was built around a conceptual framework for the elucidation of photophysical and photochemical phenomena in atoms, molecules, van der Waals complexes and clusters, condensed phases, poly mers and biological supermolecules. The interdisciplinary nature of this research field was deliberated by intensive and extensive interactions between scientists from different disciplines and between theory and experiment. This volume provides a record of the invited lectures at the Symposium.

The amazing growth of computational resources has made possible the modeling of complex chemical processes. To develop these models one needs to proceed from rigorous theoretical methods to approximate ones by exploiting the potential of innovative architectural features of modern concurrent processors. This book reviews some of the most advanced theoretical approaches in the field of molecular reaction dynamics in order to cope as rigorously as possible with the complexity of real systems.
