Data for Photodissociation of Some Small Molecular Ions Relevant for Astrochemistry and Laboratory Investigation

Abstract

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 radiative processes involving some non-symmetric systems relevant for astrochemistry: data needed for modeling

“…Due to the complexity of electron dynamics in molecules and the sophistication of most experimental setups used in this context, atomic and molecular (A&M) data and databases are an indispensable ingredient in new experimental approaches and accurate theoretical support (Hauschildt & Baron, 2010;Albert et al, 2020;Epée Epée et al, 2022;Srećković et al, 2021). Furthermore, one can observe the present importance of investigating the optical properties of numerous small molecules as well as the associated A&M data (Sansone et al, 2010;Djuissi et al, 2020;Iacob et al, 2019;Srećković et al, 2022;Mihajlov et al, 2011). Precision spectroscopy of molecular ions has applications in astrochemistry, quantum state controlled chemical reactions, and measurements of fundamental constants (Vázquez-Carson et al, 2022;Iacob, 2020;Brown et al, 2016;Ignjatović et al, 2020;Pop et al, 2021).…”
