Description
Gas phase studies have provided significant contributions to the understanding of activated CO$_\text{2}$. The metastable CO$_\text{2}^{\bullet-}$ is stabilized by a solvation shell and CO$_\text{2}^{\bullet-}$(H$_\text{2}$O)$_\text{n}$ can be studied readily by Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometry. An EKSPLA NT277 optical parametric oscillator system is coupled into the reaction cell, covering the 2235-4000 cm$^\text{-1}$ region at 1000 Hz pulse repetition rate. CO$_\text{2}^{\bullet-}$(H$_\text{2}$O)$_\text{n}$ (n ≈ 43) is studied via IR photodissociation spectroscopy. The products of the reaction between CO$_\text{2}^{\bullet-}$(H$_\text{2}$O)$_\text{n}$ and small organic molecules are investigated. This provides information about the formation of covalent bonds and thermochemical data via nanocalorimetry.
