摘要：
Photoabsorption spectra of several CS(N + 2)O and Cs(N) clusters were obtained by means of laser-induced beam-depletion techniques. The strong absorption of clusters with N greater-than-or-equal-to 3 in the near infrared indicates that collective motion might play an important role. Dipole transitions between molecular orbitals, enhanced by plasmon oscillations, generate remarkably distinct spectra for (a) closed-shell clusters at N = 8 and (b) geometrically symmetric clusters like Cs6O and Cs14O.
