## Abstract The excited electronic states of 2, 2โdimethylisoindene (1) have been studied by electronโenergyโloss spectroscopy. Its vertical gasโphase triplet (1^3^B~2~), and singlet (1^1^B~2~) excitation energies are 1.61 and 3.19 eV, respectively. The excited states are thus lowered by 0.49 eV an
