Abstract

Collisional relaxation as a function of energy was employed to investigate cooling and trapping of molecules in highly excited rotational states. Highly rotating diatomic molecules undergoing quasiresonant transition were used to investigate the possibility of producing super rotors. The calculations showed that the inelastic collisions were suppressed with the lowering of energy due to closing of quasiresonant rotation-vibration channels. The analysis suggested that the use of buffer gas cooling could cool the super rotors and load them into a trap without significant loss of population.
