NAME: dimethylmercury
FORMULA: Hg(CH3)2
AUTHOR(YEAR): BassLaufer(1973-1974)
T: 298K
λ: 184-254nm(max)
BIBLIOGRAPHY: A.M. Bass and A.H. Laufer, "Extinction coefficients of azomethane and dimethyl mercury in the near ultra-violet", J. Photochem. 2, 465-470 (1973-1974); DOI: 10.1016/0047-2670(74)85012-4
COMMENTS: Molecular hydrogen continuum as a light source; spectral resolution of the monochromator ∼0.005 nm

Absorption coefficients k (atm, 273K)-1 cm-1 (base e) at the absorption maxima from Table 2 and at the photochemically important wavelength of 253.7 nm have been converted to absorption cross sections (conversion factor 3.72×10-20)

For all wavelengths between 270 nm and 330 nm:
k ≤ 0.2 cm-1 atm-1, i. e., σ ≤ 7 × 10-21 cm2 molecule-1
