Wave packet propagation techniques are used to find experimentally reliable laser parameters that yield optimal production. The photoionization and photodissociation dynamics of sodium iodine molecules are interpreted into several channels. Several frequencies are found to be suitable for NaI molecules during the photoionization and dissociation processes. Photon-dressed excited states and electron-dressed ionic continuum states facilitate the search for available laser parameters.

Multi-reference configuration interaction is used to produce potential energy curves (PECs) for the excited B1\Pi state of KH molecule. To investigate the correlation effect of core-valence electrons, five schemes are employed which include the different correlated electrons and different active spaces. The PECs are fitted into analytical potential energy functions (APEFs). The spectroscopic parameters, ro-vibrational levels, and transition frequencies are determined based on the APEFs and compared with available experimental and theoretical data. The molecular properties for B1| obtained in this letter, which are better than those available in literature, can be reproduced with calculations using the suitable correlated electrons and active space of orbitals.

Nine low-lying electronic states of the AsP molecule, including \Sigma+, \Pi, and \Delta symmetries with singlet, triplet, and quintet spin multiplicities, are studied using multi-reference configuration interaction method. The potential energy curves and the spectroscopic constants of these nine states are determined, and compared with the experimental observed data as well as other theoretical works available at present. Three quintet states are reported for the first time. Furthermore, the analytical potential energy functions of these states are fitted using Murrell-Sorbie function and least square fitting method.

The multi-reference configuration interaction (MRCI) electronic energy calculations have been carried out on the ground state (X1'Sigma') as well as three low-lying excited states (3'Sigma', 1'Pi', 3'Pi') of ZnCd dimer. Potential energy curves (PECs) are therefore generated and fitted to the analytical potential energy functions (APEFs) using the Murrel-Sorbie (MS) potential function. Based on the PECs, the vibrational levels of each state are determined by solving Schrodinger equation of nuclear motion, and corresponding spectroscopic parameters are accurately calculated using the APEFs. The present values of spectroscopic parameters including equilibrium positions and dissociation energies are compared with other theoretical reports available at present.
