Request a sales quotePhotophysiology, Volume I: General Principles: Action of Light on Plants focuses on the fundamental mechanisms by which non-ionizing radiations affect the living cell at the molecular level when such analysis is possible. The selection first offers information on the development of photochemistry, including photosynthesis, photoaxis, vision, phototropism, diurnal rhythms and visible light, and medical uses of ultraviolet light. The text then takes a look at the principles of photochemistry and photochemical methods and electron spin resonance and its application to photophysiology. The publication examines the photochemical action of light on macromolecules, absorption spectra, spectrophotometry, and action spectra, and photochemical reactions of photosynthesis. Discussions focus on photosynthetic phosphorylation, measurement and interpretation of action spectra, instrumentation for absorption spectra, and inactivation of viruses by visible and ultraviolet light. The selection is a valuable source of information for readers interested in photophysiology.
