Dipole-bound anions: formed by Rydberg electron transfer (RET) and studied by velocity map imaging–anion photoelectron spectroscopy (VMI–aPES)

Abstract

Here, we demonstrate the capabilities of the unique combination of Rydberg electron transfer (RET) and velocity map imaging–anion photoelectron spectroscopy (VMI–aPES) to form dipole bound anions and to measure their photoelectron spectra. For these purposes, we have chosen the dipole bound anions of acetonitrile, ammonia–water dimer, water dimer, dimethyl sulfoxide and thymine as examples. All of these had been previously formed and/or studied but by other methodologies.
