He(I) and He(II) photoelectron spectra of benzo[b]selenophene and benzo[b]tellurophene The photoelectron spectra of benzo[ b ]selenophene ( 2 ) and benzo[ b ]tellurophene ( 1 ) have been recorded with He(I) and He(II) radiation and been compared to those of benzo[ b ]thiophene ( 3 ), benzo[ b ]furan ( 4 ), indole ( 5 ) and indene ( 6 ). The first four bands are correlated with π‐orbitals, of which the highest occupied one is strongly localized on the heteroatom in the case of 1 . The results are in agreement with semi‐empirical PPP‐calculations.
