โฆ Synopsis
Initial rotational (and for the H, reaction, vibrational) quantum-state distributions of ZnH (ZnD) formed in the exoergic reactions of Zn( ) with H,, D,, and HD were determined. Unusual isotope effects are observed, and is postulated that product rotational energy is a result of an angular dependence of the exit-channel potential in the decomposition of H-Zn-H, H-Zn-D, and D-Zn-D insertion intermediates.

The initial bimodal distributions of product MgH( u=O) rotational states in the reaction of Mg( 'P, ) with H2 or HD are found to be identical.

X-ray crystallographic analyses are reported for the two title compounds (8 and 9), of which the former crystallized in two modifications (8n and 8b). In all three structures, the pyranose rings have the %, (D) conformation and the substituents at C-l are axial and those at C-24-4 are equatorial. Th
