Reactivity of Sodium Chloride Clusters with Formic Acids in the Gas Phase by Theoretical Study

As increasingly facing the effects of global warming, it is important to identify and study the major climate drivers. Aerosols represent one of these major climate drivers and, thus, receive particular scientific and political attention. Aerosols contain organic and inorganic compounds that significantly affect radiative forcing. Sea salt aerosol is one of the most important aerosols in the earth's atmosphere and has important effects on the earth's climate. As the main component of sea salt aerosols, sodium chloride is involved in many atmospheric processes, such as cloud formation, photochemical reactions, and reactions with atmospheric trace gases. Gas clusters are ideal models for studying the basic physical and chemical properties of pure and doped salts. In previous experiment, gas-phase sodium chloride cluster ions are used to model chemical reactions in sea salt aerosols by A Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer and electrospray ionization (ESI). Formic acid is used as reaction gas. It recorded reaction kinetics and absolute rate coefficients. There are difference between different kinds of cluster. Because there are many kinds of structures for sodium chloride. To find reaction structures and explain experiment results, this study calculates reactivity of sodium chloride clusters with formic acids in the gas phase.
