Study of the vaporization of LiI, LiI/C-70, LiI/LiF/C-70 from a Knudsen cell located in the ionization chamber of a mass spectrometer
Апстракт
The vaporization of LiI, LiI/C-70 and LiI/LIF/C-70 was studied using a Knudsen cell located in the ionization chamber of a magnetic sector mass spectrometer in the temperature range from 350 degrees C to 850 degrees C. The ion species, LinI+ (n = 2, 3, 4 or 6) were identified from the mixture LiI/C-70, while the clusters LinI+ and LinF+ (n = 2, 3, 4, 5 or 6) were detected from a mixture LiI/LiF/C-70. The intensities of LinI+ were higher than the emission of LinF+ cluster when the ratio of LiI to LiF was 2:1. By contrast, the emission of LinF+ is favored when the ratio of LiI to LiF was 1:2. These results show that the vaporization of a mixture LiI/LIF/C-70 from a Knudsen cell located in the ionization chamber of a mass spectrometer represents an efficient and simple way to obtain and investigate clusters of the type LinX, X = F or I. In this work, it was also shown that the trends of the In (Intensity, arb. units) versus temperature for all LinI+ clusters below and above the melting po...int of LiI were not same. This suggested that the manner of formation of these clusters could be different due to changes in temperature.
