✦ Synopsis

If

C is a p-ary code of length n and a (1) and a (2) are two codewords, then a (3) is called a descendant of a (1) and a (2) if a~ 3) E {a? ), al 2) } for i = 1 ..... n. We are interested in codes C' with the property that either any two nonintersecting coalitions of size 2 have no common descendant or the descendant of any coalition of size 3 does not belong to the code. We construct such codes based on Hadamard matrices.

The structure of the heteroatom-substituted 3 -phosphaalkyne [(H 3 C 2 CH] 3 Si-O-C P (1) was derived from the 31 P, 13 C, 29 Si and 17 O NMR spectra. The phosphorus atom of the non-isotope-enriched compound exhibits an extremely negative 31 P 13 C one-bond and 31 P 18 O two-bond isotope shift of 0.
