DATAFILE: CH2O_Mentall(1971)_298K_120-177nm.txt
NAME: formaldehyde, methanal
FORMULA: CH2O
AUTHOR(YEAR): Mentall(1971)
T: 298K
λ: 120-177nm
BIBLIOGRAPHY: J.E. Mentall, E.P. Gentieu, M. Krauss, and D. Neumann, "Photoionization and absorption spectrum of formaldehyde in the vacuum ultraviolet", J. Chem. Phys. 55, 5471-5479 (1971); DOI: 10.1063/1.1675711
COMMENTS: High-resolution (0.025 nm) absorption measurements using as light sources the Ar, Kr, Xe, and H2 continua

Absorption coefficients k (atm, 273 K)-1 cm-1 (base e) plotted in Fig. 1 have been digitized and converted to absorption cross sections (conversion factor 3.72×10-20)
