2. LASER wavenumbers AK: 200307, REMPI spectra recorded for max intensities of all ion Species; Hence signal near 21654.5 (86618 cm-1 = 2 x hv excitation) Drops out in lower spectrum since resonance signal is lower than “background” signal (which most probably is due to C+). Width of spectrum is about 4 cm -1 on 2 x hv excitation scale Fig. 2
