A modified coupled cluster method is applied to the research of the ground-state energy of periodic systems described by model Hamiltonians. The reference function is always a strongly localized function. The method is applied first to Heisenberg Ž . Hamiltonians and spin-frustrated one-dimensional

## Abstract The non‐classical 1,2‐diboretane‐3‐ylidene **1a** was studied by ^13^C and ^29^Si NMR spectroscopy in order to obtain coupling constants ^1^__J__(^13^C,^11^B) and ^1^__J__(^29^Si,^13^C). The magnitudes of ^1^__J__(^13^C,^11^B) were deduced from linewidth measurements in low‐temperature
