Sauvageau, C. Sandorfy Title: The electronic spectra of n-alkanes Journal/Source: J. Mol. Spectroscopy, 24, 253-269, (1967); doi:10.1016/0022-2852(67)90089-6 Data: Energy/Wavelength range: > 115 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: Phase: pH: Comments: The far ultraviolet absorption spectra of the eight first normal paraffin hydrocarbons were measured down to 1150 Å. Methane has a diffuse but not entirely structureless band system with a maximum at 1277 Å. Author to whom correspondence should be addressed: (e-mail address):
