“…In addition to these PES and PIE studies, the IE of V -bz 2 was measured as 6.16 ͑2͒ eV from Rydberg series in the near-ultraviolet absorption spectrum of the vanadium complex. 9 The large error reported in that study is somewhat surprising because Rydberg spectroscopy should in principle yield accurate ionization limits. However, the absorption spectrum of V -bz 2 was rather broad and the value of the quantum defect was not well defined in the original paper.…”

“…2,3 Table III compares the IE values of Ti-and V -bz 2 obtained from ZEKE spectroscopy with those from previous PES, 6,8 PIE,4,5,7 and Rydberg absorption spectroscopic measurements. 9 It can be seen from the table that accuracy of the Ti-and V -bz 2 IE values is greatly improved by this work due to very high ZEKE spectral resolution. The previous PES measurements reported a very large uncertainty ͑0.5 eV͒ for the IE of Ti-bz 2 .…”

“…The absorption spectrum 43 of CrBz 2 vapor in the 2.7-5.3 eV range shows relatively narrow Rydberg transitions at 3.3 and 4.4 eV and a broad feature at $4.0 eV, which is assigned to a valence excitation. p* transition at $7.0 eV and two molecular excitations at $2.6 and 3.8 eV, both of which have been assigned 43 to transitions originating from the e 2g (HOMO-1) orbital. A recent calculation 44 using time-dependent DFT places the CrBz 2 a 1g !…”

“…Transition metal sandwich compounds appear to reveal in the gas-phase absorption spectra interesting features which arise from electronic transitions originating at the non-bonding metal a 1 (d z 2) level and terminating at Rydberg MOs. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Molecular Rydberg orbitals are derived from the AOs with principal quantum numbers higher than those for valence-shell MOs. 20,21 They are atomic-like and can be characterised by azimuthal quantum numbers l. The l value determines the type of a Rydberg MO (s, p, d, ...).…”
