Abstract :
A new approach for cavity-mediated optical cooling of molecules in harmonic traps is investigated using vibrational transitions in the infrared regime. Ab initio methods are used to determine transition dipole moments of the rovibrational modes, the lifetime of the rovibrational states and the polarizabilities. Theoretical results predict cooling of molecular ions into the ground state of the trap on a sub-milisecond time scale.
