The electronic structure of the fluorine molecule

Abstract

Evidence is being presented that F 2 has a different type of electronic structure than have Cl 2, Br 2, I 2, as suggested by the quanticule theory. The internuclear distance, the vibrational force constant and their changes on excitation for F 2 do not agree with those expected for the structures X + e 2X + and X + e 2Y +, which fit the 3 other halogen and interhalogen molecules respectively.
