Photoelectron Photoion Coincidence Spectroscopy of NCl(3) and NCl(2)

We investigate NCl(3) and the NCl(2) radical by photoelectron‐photoion coincidence spectroscopy using synchrotron radiation. The mass selected threshold photoelectron spectrum (ms‐TPES) of NCl(3) is broad and unstructured due to the large geometry change. An ionization energy of 9.7±0.1 eV is estima...

Sumario:We investigate NCl(3) and the NCl(2) radical by photoelectron‐photoion coincidence spectroscopy using synchrotron radiation. The mass selected threshold photoelectron spectrum (ms‐TPES) of NCl(3) is broad and unstructured due to the large geometry change. An ionization energy of 9.7±0.1 eV is estimated from the spectrum and supported by computations. NCl(2) is generated by photolysis at 213 nm from NCl(3) and its ms‐TPES shows an extended vibrational progression with a 90 meV spacing that is assigned to the symmetric N−Cl stretching mode in the cation. An adiabatic ionization energy of 9.94 ± 0.02 eV is determined.
