T: 298K
λ: 200.7-237.5nm
BIBLIOGRAPHY: A.B. Rocha, A.S. Pimentel, and C.E. Bielschowsky, "Direct investigation of the validity of vertical approximation in the calculation of transition moment matrix elements: n → π* transition in methyl formate", J. Phys. Chem. A 106, 181-183 (2002); DOI: 10.1021/jp012647r
COMMENTS: Medium-resolution (≈ 0.6 nm) absorption measurements at 200.7-260 nm usig a diode array spectrometer

Data points for the absorption cross sections, plotted in Fig. 1 together with those measured by

E. Vésine and A. Mellouki, "UV absorption cross sections for a series of formates", J. Chim. Phys. Physico-Chim. Biol. 94, 1634-1641 (1997); DOI: 10.1051/jcp/1997941634,

have been digitized between 200 and 238 nm (for wavelengths above 238 nm the absorption cross sections are identical to those of Vésine and Mellouki)
