Construction of Proton Nuclear Magnetic Resonance Database System with Full Spectral Patterns

Abstract
A data file structure of a 1H-NMR database with a full spectral pattern is described together with the registration procedure. The 1H-NMR data file comprises two master and one access files. One of the master files is a data file for a digitized spectral pattern (MASTER FILE II) and the other includes information concerning the spectrum (MASTER FILE I). For both files, some expenditures are made to compress the data for the reduction of the memory size in the database. An example of output of a 1H-NMR spectrum is given. The problems in constructing the 1H-NMR database system are discussed.
