RESUMO:

In this thesis, in the context of Atomic and Molecular Physics, we present a study about the NaLi and RbCs molecular systems for the ground state. We take a spectroscopic approach using experimentally obtained results for vibrational energies, and we use a mathematical structure constructed from coherent states to construct an eective algebraic Hamiltonian. At this time, we use operators belonging to a particular Lie algebra to determine the mathematical expression used in the calculation of vibrational energy, to be compared with the energies obtained by experimental methods. Thus, we want to calculate the linear parameters, which will be used to calculate the dissociation energy, the range and consequently the construction of the Potential Energy Curves of the molecular systems under study. For minimization of experimental and calculated energies, we use fortram coding, whose purpose is to obtain such parameters, as well as to obtain the results of the algebraically calcula- ted energies. In algebraic computation we will make an adjustment for the minimization between energies, such that they will be used in the construction of the agenic potential. To construct the Potential Energy Curves, we will use a Morse type expansion, in which we will have as elements values associated with the number of bound states of each molecular system and the number of expansion terms. Thus, oer to the academic community a theoretical material with reference in experimental data about the NaLi and RbCs molecules, using an elegant mathematical formalism that can contribute to the dissemination of knowledge to the actors involved in pure and applied research in physics or related elds.
