Electron attachment products of methylene chloride in solid argon: an experimental and quantum chemical IR spectroscopic study

The nature and structure of electron attachment products in the photoinduced electron transfer reaction DMA + CH 2 Cl 2 → hv DMA + + ( electron attachment products ) in solid argon has been studied by FTIR spectroscopy (DMA = N,N-dimethylaniline, hν = 4.88 eV Hg lamp radiation) along with extensive...

Description
Summary:The nature and structure of electron attachment products in the photoinduced electron transfer reaction DMA + CH 2 Cl 2 → hv DMA + + ( electron attachment products ) in solid argon has been studied by FTIR spectroscopy (DMA = N,N-dimethylaniline, hν = 4.88 eV Hg lamp radiation) along with extensive ab initio calculations. Two attachment products have been identified: the radical anion of CH 2Cl 2 and the dichloromethane anion (HCCl 2 −. The radical anion turns out to have a C 1 hydrogen bridged structure (ClHCH…Cl −1). This structure as well as the species of HCCl 2 − have not been detected before.
