Two spin-doublet states in {sub {lambda}}{sup 7}Li are studied on the basis of the {alpha}+{lambda}+n+p four-body model. We employ the two-body interactions that reproduce the observed properties of any subsystems composed of {alpha}N,{alpha}{lambda}, {alpha}NN, and {alpha}{lambda}N. Furthermore, the {lambda}N interaction is adjusted so as to reproduce the 0{sup +}-1{sup +} splitting of in {sub {lambda}}{sup 4}H. The calculated energy splittings of 3/2{sup +}-1/2{sup +} and 7/2{sup +}-5/2{sup +} states in {sub {lambda}}{sup 7}Li are 0.69 and 0.46 MeV, which are in good agreement with the recent observed data. The spin-dependent components of the {lambda}N interaction are discussed.
