“…The importance of studying optical properties in different fields, especially when modelling those systems, is of particular interest [5][6][7]. If the required data, i.e., information, are available, we can simulate the spectral properties [8][9][10][11].…”

The calculated photodissociation data of some small molecular ions have been reported. The cross-sections and spectral rate coefficients data have been studied using a quantum mechanical method. The plasma parameters, i.e., conditions, cover temperatures from 1000 to 20,000 K and wavelengths in the EUV and UV region. The influence of temperature and wavelength on the spectral coefficients data of all of the investigated species have been discussed. Data could also be useful for plasma diagnostics in laboratory, astrophysics, and industrial plasmas for their modelling.

The study of the influence of numerous atomic and molecular processes may be of importance for diagnostic methods required to obtain physical conditions in the broadline region (BLR) of active galactic nuclei (Dimitrijević et al 2021, Srećković et al. 2020). Collisional ionization processes in atom-Rydberg atom collisions, along with the associated recombination processes, have been studied and reported among several collisional reactions. In moderately ionized plasma layers, these processes have an impact on ionization and the populations of hydrogen excited atoms. From the results it follows that the investigation of these processes is of interest for the research and modelling of such a medium.

Electron-impact processes involving molecular ions provides valuable insights into the chemical complexity and dynamics of astrophysical environments. These processes are particularly important in understanding the chemistry and dynamics of astrophysical environments such as interstellar clouds and planetary atmospheres (Dimitrijević et al. 2021, Srećković et al. 2020). Understanding electron-impact processes in astrophysics requires a combination of theoretical modeling, laboratory experiments, and observational data (Albert et al. 2020). Here we report the new data for electron-impact processes involving some small molecular ions (potassium, sodium, lithium and hydrogen molecular cations). Data includes rate coefficients for electron-impact processes in domains of higher principal quantum numbers and temperatures up to 10 000 K.
