Photoelectron Imaging of Anions Illustrated by 310 Nm Detachment of F−

This method can help answer key questions in the electron scattering molecular spectroscopy and reaction dynamics field, such as the nature of molecular orbitals, molecular electronic structure, vibrational energy levels, and the nature of scattering and auto-detachment resonances. The main advantage of this technique is that it's highly efficient, recording an entire photoelectron spectrum and angular distribution in a single image. To begin generating anions, apply a backing gas or gas mixture behind the pulsed nozzle.

Operate the nozzle at 10 hertz. Set the nozzle duration on the digital delay generator Channel A.Then, trigger the pulsed nozzle driver to inject the gas into discharge. Using Channel C on the digital delay generator, apply the high voltage discharge pulse V1.To monitor the anion mass spectrum, first put the instrument into ion mode.
