Separación isotópica de Si mediante la DMFIR con dos frecuencias [PDF]
, 2017 InfraRed Multi-Photon Dissociation (IRMPD) is a highly selective laser isotope separation technique. This process consists of a sequential IR photon absorption from the ground vibrational state up to dissociation by a molecule that contains the isotope ...

Annals of the New York Academy of Sciences, 1976 Separation processes for isotopes based on irradiation of a molecule with a laser tuned to a frequency matching a vibrational state of a particular isotope of the molecule are described. Separation of U isotopes is mentioned briefly. A CO/sub 2/ laser and a filtered uv flashlamp have been used for the separation of B isotopes using a two-photon ...
