    "abstract": "A novel result concerning Raman coupling schemes in the context of trapped\nions is obtained. By means of an operator perturbative approach, it is shown\nthat the complete time evolution of these systems (in the interaction picture)\ncan be expressed, with a high degree of accuracy, as the product of two unitary\nevolutions. The first one describes the time evolution related to an effective\ncoarse grained dynamics. The second is a suitable correction restoring the {\\em\nfine} dynamics suppressed by the coarse graining performed to adiabatically\neliminate the nonresonantly coupled atomic level.",
