OECD Guidelines for the Testing of Chemicals / Section 1: Physical-Chemical properties Test No. 101: UV-VIS Absorption Spectra

OECD Publishing
2

This Test Guideline describes the determining of the ultraviolet-visible (UV-VIS) absorption spectrum of a chemical compound to have some indication of the wavelengths at which the compounds may be susceptible to photochemical degradation. Degradation will depend upon the total energy absorbed in specific wavelength regions. The absence of measurable absorption does not preclude the possibility of photodegradation. This method utilises a double-beam spectrophotometer which records only the absorption differences between the blank (the solvent and all present chemical species other than the test chemical) and test solutions to give the spectrum of the chemical being tested. The test should be carried out at 25°C. The test solutions should be made up in a concentration which will result in at least one absorbance maximum in the range 0.5 to 1.5 units.

OECD Factbook 2014 is a comprehensive annual statistical publication. More than 100 indicators cover a wide range of topics including new indicators on trade in value added and climate change.

Data are provided for all OECD member countries (including area totals), and for Brazil, China, India, Indonesia, the Russian Federation and South Africa. For each indicator, there is a two-page spread: a text page includes a short introduction followed by a detailed definition of the indicator, comments on comparability of the data, an assessment of long-term trends related to the indicator and a list of references for further information on the indicator; the second page contains a table and a graph providing, at a glance, the key message conveyed by the data. Each indicator includes "StatLinks" which allow readers to download the corresponding data.

OECD Countries covered include Australia, Austria, Belgium, Canada, Chile,Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Israel, Italy, Japan, Korea, Luxembourg, Mexico, Netherlands, New Zealand, Poland, Portugal, Slovak Republic, Slovenia, Spain, Sweden, Switzerland, Turkey, the United Kingdom, and the United States. Non-OECD countries covered include Brazil, China, India, Indonesia, Russia, and South Africa.

Topics covered include population and migration; production and productivity; household income, wealth and debt; globalisation, trade and foreign direct investment (FDI); prices, interest rates and exchange rates; energy and transportation; labour, employment and unemployment; science and technology including research and development (R&D) and the Information and Communications Technology (ICT) sector; environment including natural resoures, water,and air and climate; education resources and outcomes; government expenditures, debt, revenues, taxes, agricultural support and foreign aid; and health status, risk and resources.

The OECD Factbook is also available as a free app for your mobile device! Visit your app store.
