We have used the effective‐mass approximation and a variational procedure in the study of internal transitions associated with 1s‐, 2p‐, 3p‐, and 4p‐like magneto‐exciton confined states in GaAs–(Ga, Al)As quantum wells, under a magnetic field applied in the growth direction. Theoretical results were obtained as a function of the applied magnetic field and for several well widths. The calculated far‐infrared intraexcitonic transition energies are found in good agreement with recent experimental measurements obtained via a highly sensitive optically detected resonance technique.
