Abstract
Recent advances in the control of atoms, molecules, and ions, such as laser cooling and trapping, allowed the development of spectroscopic techniques with various applications, including the test of fundamental laws of physics. For this reason, there is a growing interest for molecular systems with properties that allow precise measurements of charge-parity symmetry violating interactions, the electron electric dipole moment, and thetime variations of fundamental constants. In this context, the use of computational chemistry, especially highly correlated methods, is extremely useful as it allows the prediction of atomic and molecular properties with high accuracy. The goal of this project is the determination of spectroscopic properties of candidate molecular ions for experiments searching for varying proton-to-electron mass ratio, m_p/m_e, by the use, development, and improvement of computational tools.
