The geometry and the n-electronic structure of 6,7-dimethyl-3-oxabicyclo[3.2.O]hepta-l,4,6triene (4) is analyzed by M N D O calculations and by the interpretation of the He-I-photoelectron spectrum. The calculated bond length alternations in 4 indicate olefinic resp. antiaromatic character. As H O M
