A study of the rapid variations of the line profiles of λ Scorpii leads to the following new result: we find evidence for the presence of at least 5 periodicities in the intrinsic variations of λ Scorpii, which seem to be part of an equidistant multiplet. The modes associated to these periodicities are interpreted as non radial pulsation modes.
