Biological Events Probed by Ultrafast Laser Spectroscopy summarizes the progress in the experimental and theoretical understanding of primary phenomena occurring in biology on a picoseconds and nanosecond time scale. This book includes basic principles, survey of research results, and thinking of experts in the fields of photosynthesis, vision, hemoglobin, and DNA. This reference is organized into five parts. The primary events in the various areas of biology are reviewed in the first four parts. The last part covers the picosecond and subpicosecond laser techniques. Primary processes in photosynthesis are then discussed. This is followed by chapters on fluorescence and absorption kinetic measurements in higher plants. Subsequent chapters cover kinetic measurements in bacteria photosynthesis, theories of primary energy transfer appropriate to photosynthesis, and multiexcitation processes. Part II examines primary visual processes, including kinetic experimental work on rhodopsin and bacteriorhodopsin, and theoretical concepts on primary events in vision. The third part presents the introductory materials on the kinetic models of hemoglobin and myoglobin. It also discusses the interesting picosecond measurements on these proteins. Part IV focuses on the application of modern ultrafast temporal techniques to the study of DNA and its components, as well as DNA-dye complexes. The concluding part introduces the principles of design and operation of the solid state laser and picoseconds spectroscopy methods. A discussion on pulse generation methods and measurement techniques applicable for measuring primary events in biological systems is provided. This book is useful both for the newbies and experts in the field of ultrafast phenomena. It aims to attract biologists, chemists, physicists, and engineers who are interested in biological processes. It will help readers find all the necessary and relevant material in one presentation.
