Abstract
Doppler-free two-photon spectroscopy with cw and pulsed Fourier transform limited light sources allows the resolution of the rotational structure of the electronic spectrum of large molecules. Besides a very detailed analysis of the spectrum and a precise determination of spectroscopic constants, the observation of the decay behavior of individual levels is made possible in this way. Examples are presented for the prototype molecule benzene, C6H6. While regular behavior prevails in the 141 0-band at low vibrational excess energy, it is shown that strong coupling to background states occurs in the 141 011 0- band at intermediate excess energy. A detailed model for this coupling is presented.
