The {Lambda}{sub c}(2940){sup +} baryon with quantum numbers J{sup P}=(1/2){sup +} is considered as a molecular state composed of a nucleon and D{sup *} meson. We give predictions for the width of the radiative decay process {Lambda}{sub c}(2940){sup +}{yields}{Lambda}{sub c}(2286){sup +}+{gamma} in this interpretation. Based on our results we argue that an experimental determination of the radiative decay width of {Lambda}{sub c}(2940){sup +} is important for the understanding of its intrinsic properties.
