Comments: The absolute valence shell photoabsorption spectra of the first eight members of the homologous linear (normal) alkane series, 
CH4 to C8H18, have been obtained from electron energy loss measurements using dipole (e, e) spectroscopy at a resolution of 1 eV fwhm 
in the equivalent photon energy range 7-220 eV. Absolute oscillator strengths (transition probabilities) for discrete and continuum photoabsorption transitions have been determined throughout the entire energy range.
