Absolute Rate Constant for the Reaction H + H2CO
J. Chem. Phys., 1972, 57, 520.
Abstract
The photolysis of formaldehyde in the pronounced absorption region ~1700-1760 A
has been investigated. The production of H atoms has been established by direct
observation using pulsed photolysis and time dependent observation of the
Lyman-alpha resonance fluorescence at 1216 A. From the measurement of the H-atom
decay under pseudo-first order conditions the rate constant for the reaction (58) has been obtained. The result is
shown below.
