A novel empirical approach for the structure elucidation of disilanes by empirical estimation of their 29Si chemical shifts

In 13C NMR spectroscopy, there are many empirical methods for fast and exact computation of 13C chemical shifts; comparable procedures for 29Si NMR chemical shifts are not existing or are older than 20 years. On basis of the largest database of 29Si chemical shifts available, along this paper a relatively simple procedure for the similarly exact calculation of the 29Si chemical shifts of disilanes (average margin of error ca. 3.7 ppm) is given. q 2005 Elsevier B.V.
