Development of a new photoelectron spectroscopy instrument combining an electrospray ion source and photoelectron imaging

Rev Sci Instrum. 2010 Dec;81(12):123101. doi: 10.1063/1.3505097.

Abstract

A new apparatus has been constructed that combines electrospray ionization with a quadrupole mass filter, hexapole ion trap, and velocity-map imaging. The purpose is to record photoelectron images of isolated chromophore anions. To demonstrate the capability of our instrument we have recorded the photodetachment spectra of isolated deprotonated phenol and indole anions. To our knowledge, this is the first time that the photodetachment energy of the deprotonated indole anion has been recorded.
