Title: Daylight fingerprints
Long Title: IUPAC Gold Book - Daylight fingerprints
DOI: 10.1351/goldbook.11432
Status: current

Definition
Path fingerprints that are generated from a structure where atoms are described by atomic number and aromaticity; bonds are described as single, double,
 triple, or aromatic; and the results are hashed into a bit string of fixed length.

Note
Although these fingerprints were originally described by Daylight CIS, many other investigators have also implemented them.
