I. Novak et al., HE-II PHOTOELECTRON-SPECTRA OF BIFURANS AND THIENYLFURANS, Journal of electron spectroscopy and related phenomena, 69(2), 1994, pp. 177-180
He II photoelectron spectra of isomeric bifurans and thienylfurans hav
e been recorded and are assigned by comparing He I/He II intensity var
iations. The assignment agrees with the previous study of these molecu
les, where spectral interpretation was based on MO calculations and MO
correlations within the title series. He I and He II spectra are repo
rted for the new 3,3'-bifuran compound. Trends in the electronic struc
ture within the bichalcophene series are discussed.
