Download or read book Laser Picosecond Spectroscopy and Photochemistry of Biomolecules written by V. S. Letokhov and published by CRC Press. This book was released on 1987 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an up-to-date critical review of the applications of picosecond and femtosecond laser pulses in biophysics and photobiology. Ultrashort laser pulses have proved to be invaluable for the investigation of the processes taking place in complex biomolecules, where there are many possible pathways via which excitation energy may transfer and relax, and for the study of the primary states of photobiochemical reactions that occur immediately after absorption of a light quantum. Many exciting results have already emerged, and in this book the contributors, who are all expert workers at the forefront of the field, review investigations carried out in the USSR and elsewhere. Many of the most recent data from Soviet work are presented here in for the first time in English outside the specialist journals. The book begins with an introductory chapter on the general principles and methods involved in the application of ultrashort laser pulses to the study of biomolecules. The remaining chapters deal with experimental work on specific biomolecules: ultrafast processes in rhodopsins, excitation energy redistribution in metallo porphyrins, energy migration and trapping in bacterial photosynthesis, two-quantum photophysics and photochemistry of thymine, picosecond uv inactivation of viruses and bacteria and picosecond laser photochemical synthesis of organic molecules. The work discussed in the monograph lies at the juction between many disciplines - spectroscopy, quantum electronics, biophysics and biochemistry - and this review will therefore to be of interest to a wide community of researchers, and the contributors hope it will therefore encourage further collaboration in this exciting field where much still awaits discovery.

Download or read book Laser Photodissociation and Spectroscopy of Mass separated Biomolecular Ions written by Nicolas C. Polfer and published by Springer Science & Business Media. This book was released on 2013-09-03 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This lecture notes book presents how enhanced structural information of biomolecular ions can be obtained from interaction with photons of specific frequency - laser light. The methods described in the book "Laser photodissociation and spectroscopy of mass-separated biomolecular ions" make use of the fact that the discrete energy and fast time scale of photoexcitation can provide more control in ion activation. This activation is the crucial process producing structure-informative product ions that cannot be generated with more conventional heating methods, such as collisional activation. The book describes how the powerful separation capabilities and sensitivity of mass spectrometry (MS) can be combined with the structural insights from spectroscopy by measuring vibrational and electronic spectra of trapped analytes. The implementation of laser-based photodissociation techniques in MS requires basic knowledge of tunable light sources and ion trapping devices. This book introduces the reader to key concepts and approaches in molecular spectroscopy, and the light sources and ion traps employed in such experiments. The power of the methods is demonstrated by spectroscopic interrogation of a range of important biomolecular systems, including peptides, proteins, and saccharides, with laser light in the ultraviolet-visible, and infrared range. The book "Laser photodissociation and spectroscopy of mass-separated biomolecular ions" is an indispensable resource for students and researchers engaged or interested in this emerging field. It provides the solid background of key concepts and technologies for the measurements, discusses state-of-the-art experiments, and provides an outlook on future developments and applications.

Book excerpt: This Conference on biomedical applications of. lasers ~Ias organized by the Quantum Electronics Divisional Board of the European Physical Society (E.P.S.) and held at the Villa of Poggio Imperiale in Florence, September 3-6, 1979. As kno~m, laser surgery (especially microsurgery and endoscopic photo coagulation) has recently made important progress, and the field is expand i ng rapidly. Very significant applications of lasers have also been achieved in Bi ology during recent years (cell microsurgery, cell counting and sorting, cytofluorimeter devices, etc.) and the potential of laser techniques in this field is nO~1 sufficiently well establ ished. A new class of applications of laserradiJtion in Medicine has recently been made possible by important results obtained with low intensity (non coagulative) visible lasers, such as photodynamic therapy of tumors. At the same time important branches of Medicine, where light effects are studied and optical techniques are presently used for a certain number of clinical applications, such as dermatology and pediatry, appear to be still in their infancy as far as the proper use of optical radiation and techniques, and the understanding of fundamental photoinduced biological processes are con cerned. Moreover, laser photobiology appears a very promising field for the investigation of fundamental processes at the biomolecular level.
