Bayliss, A.R.H. Cole, B.G. Green Title: The Visible Absorption Spectrum of Bromine in Solution Journal/Source: Australian J. Scientific Res. A Physical Sciences, 1 (4), 472-479, (1948); doi:10.1071/CH9480472 Data: Energy/Wavelength range: Resolution: Temperature: 203 K; 298 K Temperature dependence: yes Pressure/Concentration: Phase: pH: Comments: The visible absorption spectrum of bromine was measured in n-hexane (a normal solvent) and in concentrated sulphuric acid (at room temperature and at -70° C.), phosphoric acid, and ethanol (at -70° C.) as associated solvents. The absorption continuum at 4150 A in the gas is displaced slightly to the red in n-hexane although other normal solvents may displace it to the violet. The spectra in solution are between 40 and 70 % more intense than in the gas. Author to whom correspondence should be addressed: (e-mail address):
