| Abstract: | The absorption spectra of the 127I2, 127I129I, and 129I2 isotopes of molecular iodine and the spectra of fluorescence excited by radiation of a Kr laser (λ=647.1 nm) were experimentally studied and calculated. A method for simultaneous determination of the concentration of 127I and 129I in gas mixtures (in particular, atmospheric air) is proposed. |
