General description

Double photoionization spectra of 3,4-dibromothiophene has been investigated by coincidence spectroscopy technique based on electron time-of-flight measurement.

Application

3,4-Dibromothiophene was used in the preparation of thieno[3,4-b]thiophene. It was aslo used as starting material in the synthesis of alkyl substituted, fused thiophenes.

We report the double photoionization spectra of thiophene, 3-bromothiophene, and 3,4-dibromothiophene using a coincidence spectroscopy technique based on electron time-of-flight measurements. Spectra have been recorded between the onset and 40.814 eV using He IIalpha radiation. The He I photoelectron spectrum
