science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: difluoromethane Other names: methylene fluoride; Freon 32 Formula: CH2F2 CAS-No.: 75-10-5 Study: vuv absorption spectra Authors: P. Wagner, A.B.F. Duncan Title: The Vacuum Ultraviolet Absorption Spectrum of Difluoromethane Journal/Source: J. Am. Chem. Soc., 77 (9), 2609-2610, (1955); DOI: 10.1021/ja01614a083 Data: (diagram, table, disk): Energy/Wavelength range: 53.5 - 220 nm Resolution: Temperature: Temperature dependence: Pressure/Concentration: 0.001 to 0.500 torr Comments: Four resolved electronic transitions were found with origins at about 1335, 1237, 1135 and 987 Å. Below 934 Å and extending to at least 535 Å, a region of continuous absorption was observed. Author to whom correspondence should be addressed: (e-mail address):
