The activation of classical vibro-rotational resonances in diatom molecules through slow collision processes

Zero-Energy Resonances of Hydrogen Diatom Isotopologs: Tuning Quasiresonant Transitions in Vibration Space

“…Such propensity rules have been observed experimentally at ordinary temperatures [9,10]. The remarkable properties of QRVR energy transfer have stimulated a number of theoretical studies [10][11][12][13][14][15] which have shown that the classical dynamics of the system generally plays a significant role in the collisions. Calculations have also shown that the classical mechanism persists at ultracold temperatures [13].…”
