Abstract
A cw probe laser is used to measure the time‐dependent gain on vibrational transitions of CO following a weak, pulse discharge at 100, 300, and 500 K. From the time‐dependent gain data, vibrational transfer rates are determined for endothermic processes CO(v)+CO(v=0) →CO(v−1)+CO(v=1) over the range v=2–7 at 100 K, v=2–11 at 300 K, and v=2–12 at 500 K. The measured rates exhibit a simple functional dependence on energy defect and temperature which is predicted by theories based on long‐range interactions.Keywords
