FLUORESCENCE OF THE URANYL SALTS. 



TABLE 48. Series in the fluorescence spectrum of mono-potassium uranyl nitrate. 



FIG. 80. A single group from each of the four spectra. 



1. Mono-potassium uranyl nitrate trigonal. 2. Di-potassium uranyl nitrate monoclinic. 

 3. Mono-ammonium uranyl nitrate rhombic. 4. Di-ammonium uranyl nitrate mono- 

 clinic. The bands occupy their natural positions in the left-hand panel, but have their 

 strongest bands in vertical alignment in the right-hand panel.
