Van der Waals bond lengths and electronic spectral shifts of the benzene---Kr and benzene---Xe complexes.
In: Chemical Physics Letters, Vol. 183, No. 1-2: pp. 77-83
Rotationally resolved UV-spectra are presented for the 610 bands of benzene---Kr and benzene---Xe complexes yielding precise rotational constants and van der Waals bond lengths for the ground and excited vibronic state, and electronic band shifts. These value complement the previously published data for the other rare gases and the various quantities have now been determined for all the benzene—rare gas complexes. Measured values of the bond length were used to calculate the band shifts from recent theoretical predictions. They are compared with the experimental values of this work.
