Femtosecond dynamics in ionic structures of a heart medicine

Femtosecond studies of ionic structures of milrinone - a medicine used to help the heart to recuperate its life- in water solutions show that the ICT reactions in the cation and in the anion happen in 550 fs and ∼1.2 ps, respectively. The transients also show a 2-3 ps component, assigned to cooling and twisting motion in the produced states. The result might be used for a better understanding of other functional molecules.
