Photochemistry in Nature and Applied Photochemistry
2016Several photochemical reactions of organic compounds are occurring in nature for the evolution of life and their existence on earth. Such evolutionary processes of life have been brought about by photochemical reactions of organic molecules. Among these photochemical reactions, photosynthesis of plants, vision of animals and depletion of stratospheric ...

Le spectre d'absorption, les caracteristiques luminescentes et photochimiques de la riboflavine sont presentes. L'interpretation des donnees experimentales d'autres auteurs sur la decomposition photochimique de l'eau sensibilisee par la riboflavine est critiquee.

The use of a confined space in which to carry out reactions has proven popular in recent years, as demonstrated by the large volume of work published on 'molecular microreactors' such as zeolites, micelles and nanoparticles. This article looks at reactions in microstructured reactors, also known as microchannelled reactors or microreactors. In general,

IN the course of an investigation of the ultra-violet irradiation of solid films of uracil and thymine1, certain inconsistencies were observed in the irradiation of thymine films which were unexplainable at the time and therefore not reported. Information now available has led to an investigation of the influence of humidity, more properly the vapour ...

The photochemistry of the paleoatmosphere
Journal of Molecular Evolution, 1982The ideas of Harold Urey on the origin and evolution of the atmosphere have dominated thinking in this area for 3 decades. Recent progress in this area is reviewed, with particular emphasis on photochemical modeling studies of atmospheric evolution. Research into the paleoatmosphere can be divided into 3 distinct areas: (1) The photochemistry/chemistry

Atmospheric Environment (1967), 1987
Ozone plays a major role in the atmosphere, important chemical transformations in the troposphere, stratosphere, and mesosphere all being initiated by the absorption of radiation by ozone. This article surveys laboratory data concerning the photochemistry of ozone, and indicates the relevance of the laboratory studies to interpretations of atmospheric ...

Per azione della luce ultravioletta la bilirubina disciolta in CHCl3-CH3OH somma una molecola di metanolo fornendo un prodotto per il quale si dimostra la struttura III. Tale reazione, osservata anche con altri alcooli, suggerisce la possibilita che parte della bilirubina del siero dei neonati itterici sottoposti a fototerapia venga eliminata sotto ...

Photochemistry of Carbohydrates
1963Publisher Summary This chapter discusses the information that is available on the photochemistry of carbohydrates by reference to the established principles of photochemistry and provides a basis for future work. The primary processes by which light may initiate chemical reactions is discussed.
