Abstract
The spectroscopy of the nitrate cation NO$_{3}^{+}$ remains poorly understood. It has a symmetric D$_{3h}$ ground state with an IP = 12.55 eV and is predicted to have four low lying electronic states, three of $E$ symmetry exhibiting the Jahn-Teller Effect. There have been two low resolution experiments - by photoionization spectroscopy and photoelectron spectroscopy, but evidence for the excited states is controversial. We report preliminary studies on the Threshold PhotoElectron-PhotoIon Coincidence (T-PEPICO) spectrum of the radical cation NO$_{3}^{+}$ using the DELICIOUS3 coincidence spectrometer on the DESIRS beamline at the Soleil Synchrotron. Photoelectron and photoion imaging allow us to identify the transitions to the excited states, extract the NO$_{3}^{+}$ signal from the ionization of the dominant background species NO$_{2}$ and N$_{2}$O$_{5}$, and observe vibronic spectra and dissociation dynamics of the electronic excited states.
