Isotope SeparationThe spectral selectivity of excitation with lasers allows isotopes to be
separated provided that the absorbed light can be used to effect a chemical transformation and provided that
the spectral selectivity can be maintained. We studied carbon isotope separation using the dissociation
of formaldehyde and the dissociation of CF3I as the chemical separation process.
The figure above shows how the selectivity for 13C separation in CF3I by infrared multiphoton
dissociation depends on pressure.
