We determine the elementary divisors of the Gram matrices of the
Specht modules of the symmetric group indexed by two rowed partitions.
The allows us to compute the Jantzen filtration of these modules.
Similar results are obtained for `large' primes using results of
CarterPayne and Kleshchev.
This is joint work with Gabriele Nebe.
