Structure and excited state dipole moments of oxygen containing heteroaromatics: 2,3-benzofuran
The rotationally resolved electronic spectra of the origin band of 2,3-benzofuran has been measured and analyzed. Using electronic Stark spectroscopy, the dipole moments in the ground and electronically excited state have been determined. From the values for the permanent dipole moments, the orientation of the transition dipole moment and from the geometry changes upon excitation, the lowest excited singlet state could be shown to be of L-1(b) symmetry. These results are compared to those of indole in particular. Moreover, the excited state lifetime of isolate 2,3-benzofuran in the gas phase has been determined to be 14 ns and compared to the excited state lifetime of 2,3-benzofuran in ethylacetate solution of 4 ns (C) 2020 The Authors.
