science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2019 Substance: formaldehyde Other Names: methanal; methylene oxide Formula: CH2O CAS-No.: 50-00-0 Study: uv absorption spectrum Authors: M. B. Crow, A. Gilchrist, G. Hancock, R. Peverall, G. Richmond, G. A. D. Ritchie, S. R. Taylor Title: High-Resolution Absorption Studies of the A1A2 - X1A1 202401 Band of Formaldehyde Journal/Source: J. Phys. Chem. A, 113 (24), 6689-6696, (2009); DOI: 10.1021/jp9023475 Data: diagram, table Energy/Wavelength range: 30707 - 30716 cm-1; 30630 - 30640 cm-1 Resolution: 0.0012 cm-1 Temperature: Temperature dependence: Pressure/Concentration: 450 mTorr; 700 mTorr Phase: gas pH: Comments: Absolute peak absorption cross sections and pressure broadening coefficients have been recorded. The measured absorption cross sections range between (0.18 ± 0.01) and (10.1 ± 0.08) × 10-19 cm2 molecule-1 and are considerably larger than values from the literature.
