The O(D-1)+NH3 reaction has been investigated using the improved universal
crossed molecular beam technique. Two different reaction channels, OH+NH2 a
nd NHOH/NH2O+H, have been observed. OH formation is the dominant process, w
hile the H formation process is minor. Different product angular distributi
ons are also observed for these two product channels, indicating that the t
wo reaction channels proceed with significantly different dynamics. (C) 200
