Atomic hydrogen interactions with small polycyclic aromatic hydrocarbons cation

Abstract: When exposed to a thermal beam of hydrogen atoms, gas-phase coronene cations C₂₄H₁₂⁺ can be sequentially hydrogenated. This process is accompanied by a gradual transition of the electronic structure from aromatic to aliphatic. The planar very stable coronene structure transforms into the...

The Sequence of Coronene Hydrogenation Revealed by Gas-phase IR Spectroscopy

The solar magnetic field (SMF) has historically been considered as dipole in order to build models of the radially expanding corona, that is, the solar wind in the solar minimum. The simplified approach suggests the existence of only one quasi-stationary current sheet (QCS) of solar origin in the heliosphere, namely, the heliospheric current...
