The headings of the columns of Table I, part b, were omitted and should read as follows: column 1, pH; column 2, T, O C ; column 3, 10-3k0, M-' s-I ; column 4, pH; column 5 , T , OC; column 6, 10-3ko,M-l s-'. Note the different factors for k , in parts a and b of this table.-James V. McArdle

J. M. Newsam* and T. R. Halbert: Steric Effects in [CpMoS(p-S)12 Dimers Studied by Interactive Molecular Graphics. Pages 491-494. Recent modeling of related [LMoO(p-O)], complexes indicates that distortions additional to the flexing about S2-S3 considered in the present work can occur in accommodating different ligands or conformations. The effect of these additional modes on the steric constraints and further discussion of the estimated experimental errors of the present methodology will be presented in subsequent reports.-J. M. Newsam and T. R. Halbert.
