摘要：

We show how to obtain the signs of transition dipole amplitudes from fluorescence line intensities. Using the amplitudes thus obtained, we show how to extract the highly accurate excited-state potential(s) and the transition dipole(s) as a function of the nuclear displacements, as well as the phase amplitude of unknown time evolving states. The procedures, illustrated here for the Na(2) molecule, is in principle, applicable to any polyatomic molecule.
