K. Siglow et al., ROTATIONAL ANALYSIS OF THE GROUND-STATE OF THE BENZENE CENTER-DOT NE VAN-DER-WAALS CLUSTER CATION BY RESOLVED HIGH RYDBERG SPECTROSCOPY, Chemical physics letters, 293(1-2), 1998, pp. 19-25
Series of resolved high n (40 < n < 110) Rydberg states of the benzene
Ne van der Waals cluster are measured by delayed field ionization aft
er double resonance excitation with Fourier-transform limited UV laser
pulses. A cross-correlation analysis yields the first rotationally re
solved spectrum of an aromatic molecule noble gas cluster ion, its ana
lysis leads to accurate values for the adiabatic ionization energy (AI
E = 74497.512(30) cm(-1)) of the benzene Ne cluster and the rotational
constants of the cluster ion. The average van der Waals bonding lengt
h of the Ne atom from the (benzene)(+)-plane is 3.320(2) Angstrom. (C)
