Calculations of the Lower Excited Levels of Benzene

Abstract

The energy of the first excited levels of benzene is calculated by the method of antisymmetrized molecular orbitals. The results predict two weak bands, due to forbidden electronic transitions, at λ = 2500 and λ = 2100 and a strong band at λ = 1500. No empirical data except the carbon‐carbon distance in benzene were used.
