Notes:
The one-color resonant two-photon ionization technique is employed to study jet-cooled van der Waals (vdW) clusters of halobenzene and nitrogen through the S0→S1 transition around the 0¯00 band. The spectra obtained exhibit rich information about the clusters' intermolecular vdW vibrational modes and their solvent internal rotation. We have tentatively assigned all the observed spectral features to a single isomer of C6H5X⋅⋅⋅N2 (X=F, Cl, Br). The influence of X on the vdW vibrations and the internal rotation of N2 in the complex is investigated. The analysis of the influence of X on the 0¯00 spectral shift suggests that the change in vdW interaction energy upon electronic excitation is mainly due to the dispersion term. © 1996 American Institute of Physics.
