Über Polygermane. XIX [1]. Empirische Regelin Zur Abschätzung von 13C-NMR chemischen Verschiebungen in phenylieryten Polygermanen

On Polygermanes. XIX. Empirical rules for estimating ¹³C-NMR Chemical shifts in Phenylated polygermanes ¹³C-NMR chemical shifts are given for 85 phenyl groups independently bonded to Ge in 52 acyclic and 23 cyclic Ge compounds. ¹³C-NMR phenyl signals can be estimated from basic values for perorgano substituted homonuclear chains of Ge nd from increments for substitution at the Ge atoms.
