    "abstract": "A special class of molecules that are important to many subfields in\nmolecular dynamics and chemical physics, namely free radical molecules, now\nenjoy a significant degree of center-of-mass motion control in the laboratory\nframe. The example reported in this paper concerns hydroxyl radical (OH),\nwhich, after the internal degrees of freedom are cooled in a supersonic\nexpansion, has been bunched, accelerated, and slowed using time-varying\ninhomogeneous electric fields. In situ observations of laser-induced\nfluorescence along the beam propagation path allows for detailed\ncharacterization of the longitudinal phase-space manipulation of OH molecules\nby the electric fields. The creation of a pulse containing 1e3 to 1e6 molecules\npossessing a longitudinal velocity spread from 2 to 80 m/s around a mean\nlaboratory velocity variable from 550 m/s to rest with only a few mm spatial\nextent represents an exciting and useful new experimental capability for\nexploring free radical dynamics. This paper offers the most detailed study of\nthe Stark deceleration dynamics to date.",
