  In this note, we propose an expression for the eigenvectors and scalar
products for a class of spin chains with long-range interaction and su(2)
symmetry. This class includes the Inozemtsev spin chain as well as the BDS spin
chain, which is a reduction of the one-dimensional Hubbard model at
half-filling to the spin sector. The proposal is valid for large spin chains
and is based on the construction of the monodromy matrix using the Dunkl
operators. For the Inozemtsev model these operators are known explicitly. This
construction gives in particular the eigenvectors of (an operator closely
related to) the dilatation operator of the N=4 gauge theory in the su(2) sector
up to three-loop order, as well as their scalar products. We suggest how this
will affect the expression for the quasi classical limit of the three-point
functions obtained by I. Kostov and how to include the all-loop interaction.
