In 1973, Canadian [1] and Russian [2] groups reported the observation of visible luminescence from C02 laser-irradiated molecular gases (SiF4, NH3, C2F3C) at powers well below the breakdown threshold. The extremely fast rise-time and the pressure-dependence of one part of the luminescence suggested that the molecules might be absorbing tens of photons required for dissociation under collisionless conditions. The demonstration of isotopic selectivity in the multiphoton dissociation (MPD) of a variety of molecules [3] supports this conclusion. The alluring possibility that MPD might lead to mode-selective bond breaking in molecules has also been suggested [4].
