Abstract
Relativistic effects in triphenylbismuth have been investigated using a combined experimental and theoretical approach. The influence of these effects on the molecular structure (determined by gas electron diffraction) has been evaluated by means of quantum chemical calculations which consider scalar-relativistic and relativistic effects causing electronic spin-orbit coupling. Besides the molecular structure, different types of spectroscopic techniques (IR, NMR, UV-vis) have been applied and their results have been set in contrast with the results derived from quantum chemical calculations.
