In a method of excitation and selective dissociation by absorption of the monochromatic light emitted by a high-power laser, the laser light is sent at a frequency nu 1 into an isotopic mixture of gaseous molecules in which a certain number of molecules exhibit transitions between two vibrational levels corresponding to a predetermined isotope and separated by an energy interval DELTA E1 = 2h nu 1. The molecules of a predetermined isotopic species are thus excited preferentially until subsequent dissociation into a number of constituents. |
