	Photochemistry - Wikipedia, the free encyclopedia
		Photochemistry is the study of the interaction of light and chemicals.
		The first law of photochemistry, known as the Grotthuss-Draper law (for chemists Christian J.D.T. von Grotthuss and John W. Draper), states that light must be absorbed by a chemical substance in order for a photochemical reaction to take place.
		Photochemistry may also be introduced to laymen as a reaction that proceeds with the absorption of light.

		Vincenzo Balzani 's proposes as a first law of photochemistry: "For a photochemical reaction to exist, the chemical in question must absorb light at the frequency used for irradiation." For example, green grass is green because chlorophyll (an organometallic complex) absorbs other types of light but reflects green.

		We are currently engaged in exploring the implications of photochemistry for the carbon budget.
		Preliminary results indicate that photochemistry tends to drive carbon into carbon monoxide in the upper atmospheres of these planets at temperatures and pressures where thermochemical equilibrium would dictate that methane should be the dominant carbon-bearing molecule.
		The results of the modeling has important implications for understanding how photochemistry might alter the initial carbon budget of an EGP during the course of its evolution and inward migration toward its parent star as well as for the formation of photochemical hazes that might significantly affect the emergent spectra of these objects.

	Photochemistry research could lead to cleaner environment, new sensors
		Using tools that improve by several orders of magnitude on the accuracy of microscopes and stopwatches, Lees is working at the molecular level to explore the effect of light on chemical systems.
		The field is called photochemistry and Lees’ efforts could help to find less-expensive ways to produce gasoline, make the environment cleaner and safer, and enhance the quality of microcircuitry and the equipment that relies on it.
		While most chemists work with molecules in their ground or normal states, Lees has spent the past two decades working with "excited" molecules, a state attained when molecules absorb light, known as second chemistry.

	Research in Theoretical Photochemistry
		In addition to scientific curiosity triggered by the wealth of physical and chemical processes that result from the absorption of a photon by a substrate-adsorbate complex, surface photochemistry has important implications on the development and manufacture of new materials.
		As part of its research activities in photochemistry the Theory Department, together with six European partner institutes, participates in the Research Training Network Nanoscale Photon Absorption and Spectroscopy with Electrons (NANOPHASE), which is funded by the European Commission since 2000.
		The overall topic of the network is the theory of nanometre-scale structures - atomic clusters, quantum dots on surfaces or embedded in materials, quantum wires, and molecules adsorbed on surfaces - and the spectroscopic processes that can be used to characterize those structures, their electronic and optical properties, and their growth.

		Since free radicals are the key players in Earth's oxidative atmosphere, their reactions are studied to obtain the temperature and pressure dependencies of the rate coefficients, to identify products of reactions, and to determine the reaction mechanisms.
		Since Earth's atmosphere is driven by the input of solar radiation, photochemistry plays a crucial role in determining its composition.
		Therefore, photochemistry of small molecules is studied to understand how they break apart upon light absorption.

		A provisional version of this Glossary was published in the period 1983-1984 in the Newsletters of the European Photochemical Association, the Inter-American Photochemical Society, and the Japanese Photochemical Association.The first edition of the "Glossary of Terms Used in Photochemistry" was prepared for publication in the Commission by S.E. Braslavsky and K.N. Houk.
		It is trusted that in this revised and enhanced form the Glossary will continue to serve its purpose, which is to provide definitions of terms and symbols commonly used in the field of photochemistry in order to achieve consensus on the adoption of some definitions and on the abandonment of inadequate terms.
		The Commission wants to emphasize, however, that it is not the purpose of this compilation to impose terms or rules which would hinder the freedom of choice in the use of terminology.
