We present the fine structure and Zeeman splitting of excitons localized in narrow GaAs quantum wells by interface roughness. We report an anomalous exciton identified by its intriguing magneto‐optical characteristics as a function of field strength and orientation. In the Voigt geometry, the anomalous exciton g ‐factors are 5 to 10 times larger than those for a normal exciton in this quantum dot system.
