Gowenlock, J. Trotman Title: Ultraviolet Absorption Spectra of Some Mercury Compounds Journal/Source: J. Chem. Soc., 1454-1458, (1955); DOI: 10.1039/JR9550001454 Data: table, diagram Energy/Wavelength range: 200 - 300 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: solution (ethanol) pH: Comments: The absorption spectra of ethanol solutions of some inorganic mercury compounds and of some methyl- and phenyl-mercury derivatives have been measured. The HgI2 absorption maxima are located at 215 nm (log epsilon = 4.36) and at 273 nm (log epsilon = 3.74). Author to whom correspondence should be addressed: (e-mail address):
