DATAFILE: CH2O_GentieuMentall(1970)_298K_123.6,147nm.txt
NAME: formaldehyde, methanal
FORMULA: CH2O
AUTHOR(YEAR): GentieuMentall(1970)
T: 298K
λ: 123.6,147nm
BIBLIOGRAPHY: E.P. Gentieu and J.E. Mentall, "Formaldehyde absorption coefficients in the vacuum ultraviolet (650 to 1850 Å)", Science 169, 681-683(1970); DOI: 10.1126/science.169.3946.681
COMMENTS: Photoelectrical absorption measurements between 65 and 185 nm

The data for 123.6 and 147 nm have been estimated from the absorption curve in Fig. 2 (for comparison with the own results) by

S. Glicker and L.J. Stief, "Photolysis of formaldehyde at 1470 and 1236 Å", J. Chem. Phys. 54, 2852-2857 (1971); DOI: 10.1063/1.1675264
