Cameron, V. Sivakumaran, T. J. Dillon, J. N. Crowley Title: Reaction between OH and CH3CHO Part 1. Primary product yields of CH3(296 K), CH3CO (296 K), and H (237-296 K) Journal/Source: Phys. Chem. Chem. Phys., 4, 3628 - 3638, (2002); DOI: 10.1039/b202586h Data: (diagram, table, disk): EnergyWavelength range: 220 nm Resolution: Temperature: 298 K Temperature dependence: Pressure/Concentration: Comments: The absorption cross-sections of CH3 and CH3CO radical were determined as (CH3)=(3.7±0.3)×10-17 cm2 at 216.4 nm (0.75 nm resolution) and (CH3CO)=(1.4±0.2)×10-17 cm2 at 220 nm.
