1-PHENYLPYRROLE A TICT MOLECULE?.

Abstract

1-Phenylpyrrole has been identified by several authors as a molecule that displays twisted intramolecular charge-transfer (TICT) character in the condensed phase. However, Suzuka and coworkers , \textbf{109}, 7185 (1998) and references therein.}, using single vibronic level dispersed fluorescence, observed no evidence of TICT activity in the gas phase. In this work, 1-phenylpyrrole is studied by the high resolution methods previously applied to DMABN , \textbf{ 122}, 084309 (2005).} to determine the extent of its motion along different possible TICT coordinates when it absorbs light.
