To leant more about Beer s law, use Google to find the lUPAC Glossary of Terms Used in Photochemistry. Find how the molar absorptivity of a compound (e) is related to the absorption cross section (a). Multiply the absorption cross section by Avogadro s number and note the result. How would the result change if absorbance were expressed as A = —In (P/Pq) rather than the usual definition in terms of base-10 logarithms What are the units of a Which of the quantities e or cr is a macroscopic quantity Which is a microscopic quantity Notice that the lUPAC term for molar absorptivity is molar absorption coefficient. Which of these terms is most descriptive Explain and justify your answer. 

An authoritative compilation of definitions and concepts is available in the Glossary of Terms Used in Photochemistry, 3rd edition,22 which can be downloaded from the IUPAC webpages or from those of the photochemical societies (http //pages.unibas.ch/epa or http //www.i-aps.org/). 

In 1979 G.R. De Mare replaced S.G. Bone as co-Editor of the Newsletter with H.J. Kuhn. In 1982 H. Durr joined them as the third co-Editor. The Newsletter became more and more attractive with the publication of the series History of Photochemistry (pioneers and trends), Photochemistry in Europe, Technical Reports, Topical Articles, the news about Glossary of Terms used in Photochemistry (from the lUPAC Commission) and regular news from the sister Societies (lAPS and IP A). Nevertheless, in the July 1986 issue, the Editors of the Newsletter published a complaint against the scarce contributions received from the EPA members asking for more active participation from the silent members , estimated to be 95%. 

Unfortunately, the terms photoassisted catalysis (here defined as photoinduced catalytic reaction) and photocatalysis (here described as photoassisted reaction, not including the photosensitized reactions) are recommended in the rather briefly commented "Glossary of terms used in photochemistry" [21].
