Two spin-doublet states in Λ7Li are studied on the basis of the α+Λ+n+p four-body model. We employ the two-body interactions that reproduce the observed properties of any subsystems composed of αN,αΛ, αNN, and αΛN. Furthermore, the ΛN interaction is adjusted so as to reproduce the 0+-1+ splitting of in Λ4H. The calculated energy splittings of 3/2+-1/2+ and 7/2+-5/2+ states in Λ7Li are 0.69 and 0.46 MeV, which are in good agreement with the recent observed data. The spin-dependent components of the ΛN interaction are discussed.
