Research Abstract

Radiative cooling processes of hot molecular ions were studied using an electrostatic ion storage ring. Absolute cooling rate of fullerene anion was determined with a one-photon absorption experiment, and a change in the internal temperature of zinc phthalocyanine anion was measured with a multi-photon absorption experiment. Ion-source dependence of the internal temperature of dye ion, cooling processes of oxygen molecule and gold cluster ions, and photoexcitation of relatively cold dye ion obtained with a home-made electrospray ion source were also studied.
