Propanone absorption spectrum

Evidence has also been educed for the formation of two constituents, re-ductone and l,3-dihydroxy-2-propanone, by symmetrical scission of the D-fructose molecule these constituents are mainly responsible for the peak at 285-290 m/u in the ultraviolet absorption spectrum of the D-fructose solutions. 

The absorption spectrum of l-bromo-2-propanone is compared with those of other monosubstituted acetones in figure IX-F-1 and the cross sections are listed in tabular... 

The ultraviolet spectrum of 2-propanone (acetone) is shown in Figure 9-18. The weak absorption, which peaks (i.e., has A.max) at 280 nm, is the result...
