NAME: 1,1-dibromoethene
AUTHOR(YEAR): LochtDehareng(2023)
T: 298K
λ: 112.405-247.660nm
BIBLIOGRAPHY: R. Locht and D. Dehareng, "Vacuum UV photoabsorption spectroscopic and photoionization mass spectrometric study of geminal dibromoethylene (1,1-Br2C2H2 ) in the 5-15 eV range.

COMMENTS: High-resolution (0.5 meV ~ 0.005-0.025 nm) absorption measurements using synchrotron radiation as a light source

Extinction coefficients vs. photon energy (5-11 eV) have been obtained by personal communication from Robert Locht (April 2023) and converted to absorption cross sections (conversion factor 3.8235×10-21) vs. wavelength
