Three-Dimensional CH/pi and CH/N Interactions from Quantum-Mechanical and Database Analyses

Quantum mechanical (QM)-level molecular interaction fields (MIFs) are three-dimensional potential maps that describe the intermolecular interactions surrounding a target molecule, derived through QM calculations. This study employs QM-level MIFs (MIFs(QM)) and analyses of the Cambridge Structural Database (CSD) to uncover the three-dimensional characteristics of CH/π and CH/N interactions in typical nitrogen-containing heterocyclic compounds. Our findings confirm the reliability and...
