Abstract

A combination of molecular relaxation spectroscopy and microwave conductivity experiments on model flavin compounds has resulted in the determination of the dipole moment difference in the ground and first excited singlet states. The results obtained with both methods were in excellent agreement. The dipole moment in the excited state is only slightly larger than the corresponding ground-state dipole moment. With the literature value of the S₀ dipole moment of 7.8 D, the S₁ dipole moment is then 8.8 D.
