Separation of isotopes from a mixture of respective compounds particularly UF6 compounds, containing the respective isotopes physically or, chemically by means of laser radiation by passing through a vaporous mixture, of the compounds laser radiation having a spectral width maximally corresponding to the width of the isotope shift the frequency being adjusted so, that points of accumulation of rotational vibration lines of the one compound containing the desired isotope are covered in the spectrum and the intensity, of the radiation is so high that its absorption reaches the saturation region. With a pulsed laser the duration of the radiation is shorter than the rotational relaxation time. …
