The equilibrium structures and relative stabilities of the possible 21 lower‐energy isomers for C 78 O 3 based on C 78 ( C 2 v ) were studied by intermediate neglect of differential overlap (INDO) calculations. It was indicated that the most stable geometry is 28,29,30,31,52,53‐C 78 O 3 , where three oxygen atoms are added to the same hexagon passed by the longest axis of C 78 ( C 2 v ) and epoxide structures are formed. Electronic spectra of C 78 O 3 isomers were investigated based on the optimized geometries. The blue shift of the absorptions for 28,29,30,31,52,53‐C 78 O 3 compared with that of C 78 ( C 2 v ) was rationalized and nature of transition of the peaks discussed. © 2005 Wiley Periodicals, Inc.
