Lanza, E. Jimenez, B. Ballesteros, J. Albaladejo Title: Absorption cross section determination of biogenic C5-aldehydes in the actinic region Journal/Source: Chem. Phys. Lett., 454, 184–189, (2008); http://dx.doi.org/10.1016/j.cplett.2008.02.020 Data: table, diagram Energy/Wavelength range: 255 - 330 nm Resolution: 0.19 nm Temperature: 273 - 305 K Temperature dependence: yes Pressure/Concentration: Aldehyde pressure (0.4 - 8.2 Torr, depending of the vapour pressure) Phase: vapor pH: Comments: UV absorption cross sections for 3-methylbutanal, trans-2-methyl-2-butenal, and 3-methyl-2-butenal have been determined between 255 and 390 nm and as a function of temperature (273-305 K).
