science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: acetone Other Names: dimethyl ketone; propanone Formula: CH3C(O)CH3 CAS-No.: 67-64-1 Study: uv absorption spectra Authors: I. S. Pominov, A. A. Navlova Title: Effect of temperature and salts on the UV absorption spectra of acetone and methylethylketone Journal/Source: J. Applied Spectroscopy, 9 (1), 700-702, (1968); doi:10.1007/BF00659226 Data: (diagram, table, disk): diagram Energy/Wavelength range: ~ 30000 - 45000 cm-1 (~ 222 - 333 nm) Resolution: Temperature: 183 - 293 K Temperature dependence: Pressure/Concentration: Comments: In acetone the absorption band of the C=O carbonyl group has a maximum at 275 nm. The reduction of the temperature from +20° C to -70° C leads to a reduction of the absorption coefficient from 15.4 to 12.9. Author to whom correspondence should be addressed: (e-mail address):
