COMBINATORIAL PROOF OF THE ORTHOGONALITY OF THE SECOND KIND FOR THE SPIN CHARACTERS OF $\tilde{S}n$

Using Schensted Insertion and Deletion algorithm for shifted rim hook tableaux described in [7], we construct Schensted algorithm for shifted rim hook tableaux. This give us the combinatorial proof for the orthogonality of the second kind for the spin characters of $\tilde{S}n$.
