| Abstract: | The selective multiphoton decomposition (MPD) process has the potential to provide a stand-alone heavy water process which is competitive with conventional processes. Twelve criteria are discussed for selecting a working molecule to give a process economically competitive with the Girdler-Sulphide process. The dependence of the MPD process on interacting parameters such as laser fluence, intensity and bandwidth as well as collisional effects are discussed. Finally, several potential working molecules are reviewed. |
