Description
Summary:Zero electron kinetic energy spectroscopy has been used to study the XeCl− anion and the X1/2 electronic state of neutral XeCl. The spectrum is vibrationally resolved, yielding anion and neutral vibrational frequencies. With the aid of earlier scattering measurements for the neutral state we construct a Morse–Morse-switching–van der Waals model potential function for the anion from our spectroscopic data, for which Rm=3.57±0.03 Å and ε=145.8±0.7 meV. This represents the first accurate experimental potential for the XeCl− anion.
