We report results of a systematic investigation of the energies of positive‐ion and negative‐ion states in alkan‐1‐ol molecules C n H 2 n +1 OH ( n = 1–5) in low‐energy electron impact experiments using a beam of nearly mono‐energetic electrons. The measurements have been conducted in a crossed electron‐beam/molecular‐beam apparatus wherein positive ions are detected using a quadrupole mass spectrometer whereas unstable negative ions are observed as resonance structures in the electron transmission function. Theoretical calculations of anion and cation energies have been carried out using the semi‐empirical HAM/3 technique.
