Hallquist, I. Wängberg, E. Ljungström Title: Atmospheric Fate of Carbonyl Oxidation Products Originating from alpha-Pinene and DELTA3-Carene: Determination of Rate of Reaction with OH and NO3 Radicals, UV Absorption Cross Sections, and Vapor Pressures Journal/Source: Environ. Sci. Technol., 31 (11), 3166-3172, (1997); DOI: 10.1021/es970151a Data: table, diagram Energy/Wavelength range: 277.5 - 342.5 nm Resolution: 5 nm intervals Temperature: 300 K Temperature dependence: Pressure/Concentration: Phase: vapor pH: Comments: In this investigation, ultraviolet and infrared absorption cross sections, vapor pressures, and rate coefficients for hydroxyl and nitrate radical reactions have been determined for pinonaldehyde and caronaldehyde. The infrared absorption cross sections obtained (base e) were (8.08 ± 0.32) × 10-19 and (1.04 ± 0.05) × 10-18 cm2 molecule-1 for pinonaldehyde and caronaldehyde at 1725.4 and 1741.5 cm-1, respectively.
