Electron transfer reactions of nitromethane, acetaldehyde and benzaldehyde with (H2O)n−, CO2−(H2O)n, and O2−(H2O)n, n < 110, in the gas phase

- Nitromethane, acetaldehyde and benzaldehyde form radical anions with (H2O)n−.
- With CO2−(H2O)n, the electron is transferred, and neutral CO2 evaporates.
- Nanocalorimetry yields thermochemistry of electron transfer in gas phase clusters.
- Electron transfer from O2−(H2O)n is endothermic, and is not observed.
- Evidence is found that the electron is valence-bound in CH3CHO−(H2O)n.
