The electronic transitions of 9,10-bis(phenylethynyl)anthracene (BPEA) were investigated by synchrotron radiation linear dichroism (SRLD) spectroscopy in the range 20,000–58,000 cm–1 (500–170 nm) on molecular samples aligned in stretched polyethylene. The investigation was supported by variable temperature spectroscopy and by quantum chemical calculations in the LCOAO and TD-DFT models. The combined experimental and theoretical evidence leads to characterization of several previously unobserved transitions and provides a revised polarization analysis of the visible absorption band of BPEA.
