Abstract
Principal values of magnetic shielding tensors of acetylenic carbon nuclei for butadiynyltrimethylsilane and its reorientation rate in solution have b een obtained from the interpretation of the C-13 longitudinal relaxation da ta. The ab initio GIAO-CHF calculations of shielding parameters have been p erformed and the experimental and theoretical results have been compared.
