Document Summary
Chemistry 2223b winter 2013 14 western university. This section discusses the absorption of light by organic compounds, the related photophysical processes, and the spectroscopic methods used to measure light absorption and emission. Background material, from prior chem courses, that is important is listed below. After completing this section and experiment 1, attempt: practice problems in the lab manual, 2010 and 2011 midterms: 1 6. 2012 midterm: 1 8: 2013 midterm: 1 7, 9. Colours and chromophores 2: perception of colour. White light is comprised of a continuum of different colours. If white light, such as sunlight, is passed through clouds or a prism, it can be split up into its constituent colours. The colours (wavelengths) that we can observe are in the visible region of the electromagnetic spectrum. The colour of an object that is illuminated by white light can be explained by the subtractive colour model. If the object absorbs a specific colour of light, that colour is.
