Description
We present the use of Autler-Townes effect to control the singlet-triplet state character in molecules. In a three-laser excitation scheme in lithium dimer we demonstrate that application of a strong enough coupling field to the singlet component of a singlet-triplet mixed pair leads to significant enhancement in the mixing coefficients and therefore the amount of singlet or triplet character in the pair of states which are initially mixed by the spin-orbit interaction. Our theoretical model based on solving the density matrix equations of motion gives preliminary simulations which are in good agreement with the experimental data even though
