Highly correlated MRCI wavefunctions have been used to calculate the symmetry ordering of the doublet and quartet states in the Franck-Condon region of the photoelectron spectrum of ozone. In addition, parts of the potential energy functions of the four lowest doublet states of 0; have been mapped b

## Abstract HeIα excited photoelectron spectra of pentatetraene and the inferred ionization energies are reported. The first band has a characteristic __Franck__‐__Condon__ envelope similar to the first photoelectron bands of allene and butatriene. The four bands found below 16 eV ionization energy
## Abstract The photoelectron spectrum of the title compound is reported and assigned by correlation with the photoelectron spectra of related molecules.
## Abstract The π‐ionization energies of the di‐t‐butylpolyacetylenes with two, three, four and five conjugated triple bonds have been determined by He (Iα) photoelectron spectroscopy. The assignment of the bands to the __Π__‐states of the corresponding radical cations follows from simple correlati
