Comments: Absorption spectra from 2340 to 1500 Å for dimethylformamide and from 2000 to 1220 Å for formamide are
measured. Each show two broad absorption bands. The absorption maxima for dimethylformamide are at 1974 and 1621 Å
and for formamide at 1717 and 1345 Å.
For DMF the absorption maxima taken as 1974 and 1621 have k values (k is the absolute extinction coefficient based on 1 cm
path, log10 and concentration in moles per liter) respectively of 8700 and 6960.
