英文摘要	We investigate the charmless decays of excited P-wave charmonia chi c1 ' -> VV and chi c2 ' -> VP via intermediate charmed meson loops, where V and P denote the light vector and pseudoscalar mesons, respectively. Within the model parameters, the charmed meson loop contributions are evaluated by using the effective Lagrangian approach. For chi c1 ' -> VV, the partial widths of the rho rho, omega omega, and KK channels can reach to the order of MeV, while the partial width of the Phi Phi channel is very small and in the order of keV. For chi c2 ' -> VP, the partial widths of chi c2 ' -> KK +c.c turns out to be sizeable, while the partial widths of chi c2 ' -> rho+pi-+c.c is found to be much smaller than the KK +c.c channel. Our calculations may be examined by the future BESIII experiments.
