Ab initio FSGO-pseudopotential studies are reported for the nine molecules M(LH3)4; M, L = C, Si, Ge. We report orbital energies, calculated geometries, bonding parameters, and predicted energies of reaction. Comparison with experimental data shows the results to be quite satisfactory. Comparison with the tetrahedral group IV solids affords some clues to the nature of the doped materials. The outstanding observation, from all parameters calculated, is the similarity of (Si, Ge) and their difference from carbon. Comments on possible stability of the compounds are ventured.

Semlderlvative methods have been used in the resolution of strongly overlapped reqponses In linear sweep vpltammetry (LSV). I t Is demonstrated that, although a simple form Is available only for a totally reversible eemlderlvatlve, the change in peak shape with decreasing charge-transfer reverslbillty is small. Thls permlts use of a slmple approxlmate equation for fitting all semiderlvatlves regardless ~1 reverslblllty, provided the charqe transfer Is uncompll6ated by other effects.
