We report on photoassociation of cold {sup 87}Rb atoms providing the spectroscopy of (5s{sub 1/2}+5p{sub 1/2})0{sub u}{sup +} long-range molecular states, in the energy range of [-12.5, -0.7 cm{sup -1}] below the dissociation limit. A Lu-Fano approach coupled to the LeRoy-Bernstein formula is used to analyze the data. The Lu-Fano graph exhibits the coupling of the molecular series with the (5s{sub 1/2}+5p{sub 3/2})0{sub u}{sup +} one, which is due to spin effects in the molecule. A two-channel model involving an improved LeRoy-Bernstein formula allows us to characterize the molecular series, to localize (5s{sub 1/2}+5p{sub 3/2})0{sub u}{sup +} levels, to evaluate the coupling, and to predict the energy and width of the first predissociated level of (5s{sub 1/2}+5p{sub 3/2})0{sub u}{sup +} series. An experimental spectrum confirms the prediction.
