Wy. Lu et al., RESONANT 2-PHOTON IONIZATION SPECTRA OF O-XYLENE...AR-N, P-XYLENE...AR-N, M-XYLENE...AR-N (N=1,2), Zeitschrift fur Physik. D, Atoms, molecules and clusters, 40(1-4), 1997, pp. 40-43
The resonant two-photon ionization technique (R2PI) is used to study j
et-cooled van der Waals (vdW) complexes o, p, m-xylene...Ar-n (n = 1,
2) through the S-1 <-- S-0 transition around the origin band. We have
tentatively assigned the main spectral features of these vdW complexes
. The transitions of these complexes are red-shifted from those of the
monomers. The influence of the substituent positions on the vdW vibra
tions is investigated.
