Construction of a data base for cobalt-59 nuclear magnetic resonance spectrometry

The TOOL-IR. PDB and COOD systems are compared for the construction of data bases for ⁵⁹Co-n.m.r. bibliographic and spectral data. The spectral data used are the chemical shifts from several different standards, and the line widths and coupling constants (if present). The PDB system is effective for storage and retrieval of bibliographic data, but the COOD system is better for the retrieval of spectral data, and for combination of data files on literature and chemical shifts.
