NAME: 2-methyl-1,3-butadiene, isoprene
FORMULA: CH2=C(CH3)CH=CH2
AUTHOR(YEAR): JacobsPlatt(1948)
T: 298K
λ: 173-231nm
BIBLIOGRAPHY: L.E. Jacobs and J.R. Platt, "Does ultraviolet absorption intensity increase in solution?", J. Chem. Phys. 16, 1137-1145 (1948); DOI: 10.1063/1.1746745
COMMENTS: Photographic recording of the spectrum using a vacuum fluorite spectrograph and photometric analysis

Extinction coefficients plotted in Fig. 2 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21)
