If you teach introductory organic spectroscopy then you might be interested in WinTorg, a new version (3.3) of which has just been released. WinTorg simulates the process of identifying unknown organic compounds. It is suitable for use at early university or college level. Spectroscopy is emphasised. There are 100 compounds each having pmr, cmr, ir, ms spectra and uv data and other properties. (The shareware version has only 3 compounds). The unknowns can be identified by spectroscopy alone or in combination with chemical tests. Of the several improvements and new features, the main one is the inclusion of 5 spectroscopic calculators. More information and a free demonstration version of this Windows based program are available from: http://www.chem.utas.edu.au/staff/blackman/shareware/torganal.htm Thanks Adrian Blackman (author) ____________________________________________________________________ Dr Adrian Blackman Phone: (03) 6226 2183 Int'l 61 3 6226 2183 School of Chemistry Fax: (03) 6226 2858 Int'l 61 3 6226 2858 University of Tasmania Private Bag 75 Hobart Tasmania 7001 Australia Email: Adrian.Blackman@utas.edu.au WWW: http://www.chem.utas.edu.au/staff/blackman/ajb.htm ____________________________________________________________________
