Wepropose a method for controlling a class of low temperaturechemical reactions. Specifically, we show the hydrogen abstraction channel inthe reaction of formaldehyde (H₂CO) and the hydroxyl radical (OH)can be controlled through either the molecular state or anexternal electric field. We also outline experiments for investigating anddemonstrating control over this important reaction. To this end, wereport the first Stark deceleration of H₂CO. We have decelerateda molecular beam of H₂CO essentially to rest, producing moleculesat 100 mK with a density of ~10⁶ cm^–3.
