Abstract
The spectra of polyatoinic molecules at high levels of vibrational excitation are extremely complex and are technically difficult to obtain because of very small Franck Condon factors. Stimulated Emission Pumping (SEP) technique is capable to enormously simplify such spectra by restricting the number of rotational transitions and by forcing the population of an intermediate state to the ground state using high peak power lasers. SEP spectroscopy is basically a variant of Optical-Optical-Double-Resonance (OODR) spectroscopy (figure 1).
