Popis: | SOME of the more obvious features in the spectra of scandium fluoride (ScF)1,2 and yttrium fluoride (YF)2,3 have been described. The absorption and fluorescence spectra of ScF in low temperature matrices have now been observed4, and calculations5 support the experimental finding that the ground state of ScF is 1Σ+. Some analogies6 may be drawn between the states of ScF and those of the isoelectronic molecule TiO. We have now carried out rotational analyses of a number of bands which have not been described before, and the purpose of this paper is to summarize the present position. For the most part the spectra have been observed in absorption in a carbon tube furnace at about 2,000° C, but some bands have also been photographed in thermal emission. |
