DATAFILE: CH2O_Mentall(1971)_298K_60-120nm.txt
NAME: formaldehyde, methanal
FORMULA: CH2O
AUTHOR(YEAR): Mentall(1971)
T: 298K
λ: 60-120nm
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 (0.05 nm) absorption measurements using as light sources the Ar, Kr, Xe, and H2 continua (abovve 110 nm), the Hopfield He continuum (below 100 nm), and He and H2 line sources (100-110 nm)

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)
