The 00°2 rotational population distribution and rotationally resolved linewidths are remarkably similar to those previously obtained for 00°1. Within the context of a simple physical model used to interpret the data, the similar rotational distributions and translational recoils for 00°1 and 00°2 suggest that these two states are excited by similar collision trajectories, wherein asymmetric stretching excitation is optimized when H strikes near the end of the O-C-O molecule. The magnitude of population scattered into 00°2 is -21 times smaller than that scattered into 00°1.
