Abstract  The energies , fine structures and lifetimes of the 2s2s2p 2P 0 and 2s2p2p 2D triply excited states of the Li isoelectronic sequence are calculated using multichannel saddle point and saddle point complex rotation methods. A restricted variational method is used to extrapolate a better nonrelativistic energy. The relativistic corrections are calculated with first order perturbation theory. The shifts and widths are studied with one open channel at a time as well as fully coupled open channels. The radiative transition rates and the fine structure splittings for the 2P 0 and 2D states are also calculated. These results are compared with the existing theoretical and experimental data in the literature.
