It visualizes the occupied volume of different quadrants around the gold metal center. This helps scientists understand how the "bulkiness" (steric effects) of a ligand impacts the efficiency and selectivity of a chemical reaction.
The visual data is based on computational models optimized from X-ray crystal structures . These models use a capsule-shaped volume (cylinder with rounded ends) to measure how much space atoms occupy around the central metal atom. Key Technical Details Catalyst Type: Pyrrolidinyl Gold(I) Complexes. Analysis Tool: SambVca for Buried Volume ( VBurcap V sub cap B u r end-sub ) and NEST for occupied volume quadrants.
The video illustrates the "NEST" (Non-Empirical Space-Filling Tool) analysis of pyrrolidinyl gold(I) complexes.
