LABORATORY MEASUREMENTS OF PHOTOLYTIC PARAMETERS FOR FORMALDEHYDE

The photodecomposition of formaldehyde has been studied experimentally under simulated atmospheric conditions at temperatures 220 and 300 K. Quantum yields for H2 and CO formation are reported for the spectral region 270 - 355 nm and are used to derive quantum yields for the two primary photolytic pathways. Absorption cross sections are also reported for a number of different temperatures. The data have been used to calculate CH2O photodissociation coefficients in the atmosphere as a function of altitude. (Author)
