DATAFILE: HC(O)N(CH3)2_BarnesSimpson(1963)_298K_147-234nm.txt
NAME: N,N-dimethylformamide, DMF
FORMULA: HC(O)N(CH3)2
AUTHOR(YEAR): BarnesSimpson(1963)
T: 298K
λ: 147-234nm
BIBLIOGRAPHY: E.E. Barnes and W.T. Simpson, "Correlations among electronic transitions for carbonyl and carboxyl in the vacuum ultraviolet", J. Chem. Phys. 39, 670-675 (1963); DOI: 10.1063/1.1734305
COMMENTS: The absorption spectrum (extinction coefficients vs. wavenumber) shown in Fig. 2 has been digitized, and the extinction coefficients have been converted to absorption cross sections (conversion factor 3.8235×10-21)

using a one-meter focus glass concave grating (~ 8.5 Å/mm. dispersion), arranged so that the light from the slit fell on the grating at approximately normal incidence, slit widths of 0.08 mm, and a Lyman discharge as light source
