Paperback. Condition: New. Print on Demand. This book presents the 19th-century research of Bunsen and Roscoe, revealing their groundbreaking findings on the chemical effects of light. Through meticulous experimentation, the authors established the concept of photochemical equivalence, demonstrating that the chemical action of light is proportional to its intensity and duration. Their work laid the foundation for understanding the nature of photochemical reactions, challenging the prevailing belief at the time that light acted as a catalyst without being consumed. The book delves into the fundamental principles of photochemistry, examining the factors that influence the rate of chemical reactions in the presence of light. Bunsen and Roscoe's pioneering research not only advanced the field of chemistry but also contributed to the development of photography, spectroscopy, and other areas of science that rely on the interaction of light with matter. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Paperback. Condition: New. Print on Demand. This book explores the relationship between chemical and optical extinction in a wide range of substances. The author acknowledges that many bodies reflect a notable proportion of the light which falls on them. This book builds on earlier work to demonstrate that the amount of light absorbed by these substances is directly proportional to the intensity of the light falling upon them. The author has also investigated the phenomenon of the extinction of light as it passes through various media, and has found that the rate of extinction is also proportional to the intensity of the light. These findings have important implications for our understanding of the nature of light and the interaction of light with matter. In this book, the author meticulously describes the results of extensive experimentation, laying a solid foundation for further advancements in the areas of photochemistry and the interaction of light and matter. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

(London, Taylor and Francis, 1860). 4to. No wrappers as extracted from "Philosophical Transactions" 1859 - Vol. 149 - Part II. Pp. 879-926. Clean and fine. First appearance in English of a classic paper in the investigations of chemical reactions produced by lightrays. Their joined work - from 1855-59 - founded scientific photochemistry, by determining the phenomena of induction, deduction and extinction. They found that the beginning of light reaction takes place at first very slowly and that the velocity increases gradually until it attains a constant value, observing also that steam accelerates the action and that air retards it. They also gave proofs of the "Law of Reciprocity.

Robert Bunsen and Henry Enfield Roscoe, "The Photo-chemical Researches" series, Parts 1-5 (of 6), published in the Philosophical Transactions of the Royal Society of London in 1857-1863. First appearance in English of this important series of papers that appeared in the "Annalen der Physik" as "Photochemische Untersuchungen" in 6 parts, 1855-1862. Part I, 1857: "Measurement of the Chemical Action of Light", 1857, pp 355-380, 2 plates. Part II, 1857: "Phenomena of Photo-Chemical Induction", pp 381-402, 3 plates. Part III, 1857: "Optical and Chemical Extinction of the Chemically Active Rays", pp 601-620, 1 plate (foxed). Part IV, 1859: "On the Measurement of the Chemical Action of Light" pp 489-926, 4 plates (foxed). Part V, 1863: "On the Direct Measurement of the Chemical Action of Sunlight", pp 139-160, 1 plate. All disbound from various volumes of the Philosophical Transactions. The text is general clean and crisp except for the plates which have moderate foxing. Bunsen and Roscoe's "Photo-chemical researches" is a series of papers that established the quantitative foundations of photochemistry (the study of the chemical effects of light). Key contributions included: developing an actinometer to precisely measure light's chemical effects using the reaction of hydrogen and chlorine gas, and quantifying the inverse-square law for photochemical reactions, showing that the effect is proportional to the light intensity multiplied by the exposure time (the Bunsen-Roscoe Law).

A small tear to one titlepage. All issues fine and clean. First printing of these 6 papers constituting the classical photochemical researches, - the papers laid the foundation for the science of quantitative photochemistry."Between 1852 and 1862 Bunsen collaborated with Sir Henry Roscoe on photochemical research involving the chemical combination of equal volumes of hydrogen and chlorine when they were illuminated.For this experiment they altered a reaction vessel devised by John Draper in 1843. Bunsen and Roscoe found that for some time after the experiment started - a time they called the induction period - no reation took place" then the reaktion rate slowly increased until a constant rate, proportional to the intensity of the light source used, was reached. The effect of the incident light was related to the wavelenght and followed a law of inverse squares.(they) determined that the energy of light radiated by the sun in one minute is equivalent to the energy needed for the conversion of 25x10 with a potens of 12 cubic miles of a hydrogen-chlorine mixture into hydrogen chloride."(DSB II, pp. 589).The papers contains the description of the ACTIONOMETER, which measures the heating power of electromagnetic radiation. The main use is to measure solar energy for meteteorological applications, Bunsen and Roscoe made this invention in order to carry out their researches here.The famous "BUNSEN BURNER" is first described here (in vol. 100 pp. 84-86). This invention furnished Bunsen & Kirchhoff with a non-luminous gas-flame of failrly high temperature, in which chemical substances could be vaporized and a spectrum could be obtained, due purely and simply to the luminous vapour.Leicester & Klickstein "A Source Book in Chemistry", pp. 355-360).
