science-softCon uv/vis+ spectra data base; www.uv-spectra.de, (C) science-softCon 2016 Substance: hydrogen atom Other Names: Formula: H CAS-No.: 12385-13-6 PubChem: Study: uv molar absorptivities Authors: S. O. Nielsen, B. D. Michael, E. J. Hart Title: Ultraviolet absorption spectra of hydrated electrons, hydrogen, hydroxyl, deuterium, and hydroxyl-d radicals from pulse radiolysis of aqueous solutions Journal/Source: J. Phys. Chem., 80 (22), 2482-2488, (1976); DOI: 10.1021/j100563a011 Data: table, diagram Energy/Wavelength range: ~ 190 - 300 nm Resolution: Temperature: 307 K Temperature dependence: no Pressure/Concentration: Phase: aqueous solution Comments: H atoms dissolved in liquid H2O have a distinct absorption band with maximum below 188 nm and a long wavelength slope that extends to at least 240 nm. At 188 nm epsilon = 1620 M-1 cm-1. Author to whom correspondence should be addressed: (e-mail address):
