The Molecule Kept Its Shape in One Spectrum
Graph-Laplacian fingerprints distinguish structures with identical two-dimensional connectivity without pairwise comparison.
Summary
Graph-Laplacian fingerprints distinguish structures with identical two-dimensional connectivity without pairwise comparison.
The proposed fingerprint treats a molecule as a complete three-dimensional weighted graph and compresses the graph Laplacian's eigenvalues into a fixed-length descriptor. The authors report that it separates stereoisomers and conformers that conventional two-dimensional fingerprints conflate, while remaining inexpensive enough for large chemical searches and performing competitively across several chemistry datasets. Results are computational benchmarks, not measured molecular properties.
