Introduction

In this section series of experiments are discussed which recorded a spectrum of O2+ using the new ion source. There are several advantages of using O2+  to characterise the apparatus: large ion currents are achievable, the precursor gas O2 is available at relatively low cost and high purity and the ion has a well understood photofragment spectrum. The aim of this series of experiments was to prove that the apparatus could be seriously considered as an alternative to the EI source, offer advantages in terms of rotational cooling of any spectra and generate cluster ions.
