Abstract: | Three series of paradoxical experiments on diatom-atom rotational energy transfer (RET) are reviewed. Resolution of the paradoxes leads to two propensity rules governing parity changes in RET collisions: (i) electronic spin orientation is conserved; and (ii) orbital angular momentum orientation is preserved in polar molecule-atom RET. |
