Database synopsis: spresi95

Since 1975, the All-Union Institute of Scientific and Technical Information of the Academy of Science of the USSR (VINITI) in Moscow and the Central Information Processing for Chemistry (ZIC) in Berlin have abstracted the world's chemical literature to maintain this database. This data has recently been made available to the west by InfoChem GmbH. Data were abstracted from approximately 1000 journals, and also patents, books, and other sources.

The Spresi database contains:

• journal article data (title, author, citation, keywords)
• patent data (title, author, owner, code, country)
• abstracted physical properties including density,
• melting, sublimation, boiling, decomposition points
• optical rotation constants and refractive indicies
• dissociation constants
• Jarvis-Patrick structural clustering (all versions except "preps")
