science-softCon uv/vis+ spectra data base; www.uv-spectra.de, (C) science-softCon 2019 Substance: p-tolualdehyde Other Names: benzaldehyde, 4-methyl- Formula: C8H8O CAS-No.: 104-87-0 Study: uv absorption cross sections Authors: G. Thiault, A. Mellouki, G. Le Bras, A. Chakir, N. Sokolowski-Gomez, D. Daumont Title: UV-absorption cross sections of benzaldehyde, ortho-, meta-, and para-tolualdehyde Journal/Source: J. Photochem. Photobiol. A: Chem., 162, 273-281, (2004); http://dx.doi.org/10.1016/j.nainr.2003.08.012 Data: table, diagram Energy/Wavelength range: 252 - 368 nm Resolution: 0.2 nm Temperature: 303 - 363 K Temperature dependence: Pressure/Concentration: Phase: vapor pH: Comments: The absorption cross-sections for benzaldehyde, o-tolualdehyde, m-tolualdehyde and p-tolualdehyde have been measured in the wavelength region 252–368 nm using two different systems (D2 lamp-diode array and D2 lamp-monochromator). In addition, cross sections at 253.7, 312.2 and 365 nm have been measured using a Hg pen ray lamp. Author to whom correspondence should be addressed: (e-mail address):
