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 - 290 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 HgBr2 absorption maxima are located at 206 nm (log epsilon = 3.79) and at 234 nm (log epsilon = 3.64). Author to whom correspondence should be addressed: (e-mail address):
