## Abstract A recently suggested scheme for relating ionisation potentials (__IP__) to excitation energies (__E__) has been applied to pyrazine and 2,6βdimethylpyrazine. The results indicate that in these systems the energy gap (Ξ__E__) between the two lowest lying ^1^__n__,Ο\*βstates is significan

β¦ Synopsis
The vertical iordzaticn potentials from 9-22 eV for ethylene, cycfoprppene, cyclobutene and methylene ~e~apropa~e are correlated with t%e ab initio 431G molecular orbital energies by -IP = 0.772 Ehfo -2.22 with an rms error of 0.2 eV. The result is related to the reorganization and correlation energies.
