Ultrafast spectroscopic tool for studying molecular dissociation

In summary, the results of the time-frequency analysis of the output radiation suggest that the dissociation of electronically-excited molecules can be detected with an atomic wavepacket and four-wave mixing. The arrival of the dissociation transient is evidenced by changes in the temporal history of frequency components of the wavepacket. Thus, the technique presented in this work appears to be a novel, powerful spectroscopic tool for studying the dissociation of molecules. The potential of this technique for other molecules and optoelectronic materials (such as rare earth-doped crystals) will be discussed.
