About the Book
Can be classified broadly into four areas, novel materials, surfaces and interfaces, spectroscopy and phenomena. Physical chemistry has made an impact in these areas traditionally. In novel materials, we have an article each on fullerenes, molecular magnets, self assembled monolayers, clusters and chemical sensors. All of these, needless to mention, are frontiers of chemical research. Fullerences are indeed the most intensely researched molecule of this century. It is evidenced from the fact that fullerences constitute the subject matter of some of the most cited papers in chemistry for the past several years. Molecular magnets especially ferromagnets have been vigorously pursued in the past few years. With the recent report of ferromagnetism near room temperature in molecular materials, research in this area is on the rise. Self assembled monolayers are materials for nanotechnology; a number of applications are suggested for these films and some sensors have already been developed with them. Self assembled monolayers are new additions to the area of molecular films and research in this area is picking up very fast in the past few years. Sensors again are a topic of mega research. Surfaces and interfaces have been the subject matter of intense research. Almost all of the industrial chemical processes involve heterogeneous catalysis and the chemistry occurs at surfaces. A detailed understanding of many of the catalytic processes requires studies on model systems. The molecular details especially those concerning the self organisation of molecules at surfaces and the protection these overlayers offer to corrosion are aspects of investigation. Three chapters on theoretical rotational-vibrational spectroscopy, luminescence spectroscopy and time resolved spectroscopy. In spite of the impressive advances in experimental spectroscopic research, a complete understanding of the spectra is still not achieved theoretically. Numerical results within the framework of one or another approximations are plenty but an analytical solution to the rovibrational spectrum of even simple polyatomic molecules is still a formidable task. In fact the advances have been such that the applications have spread to reaction dynamics and biological processes.

In phenomena there are three chapters, one each on chaos, ion/surface collisions and molecular relaxation in electrolyte solutions. It is now well recognised that chaos in an important aspect of biological, environmental and physical processes. Natural systems are far from equilibrium and do exhibit self organisation in time and space. This has important repercussions in science and philosophy. In the low energy regime, a number of new processes are recognised, particularly interesting are those processes where chemical bonds are broken and formed. Motion of ion in a medium has been an important problem in physical chemistry for a long time. Molecular relaxation and reaction dynamics are important areas of research and impressive array of experiments are performed today to unravel the mysteries.
