| NIST Special Publication 922 "Polycyclic Aromatic Hydrocarbon Structure Index" is presented as an aid in the identification of the chemical structures and nomenclature of 660 common (and not so common) polycyclic aromatic hydrocarbons (PAHs). This electronic version of the Structure Index allows you to browse or search to display name(s), chemical structures, Chemical Abstract Service (CAS) Registry numbers, molecular weights, and molecular descriptors. The database may be searched by name and/or molecular weight. From each structure record you can also display pages from the original print publication, and chemical structures may be downloaded as Windows metafiles or molfiles. This work was undertaken in part to provide a self-consistent source of length-to-breadth (L/B) ratio data for PAHs, and SP 922 represents the most comprehensive listing of calculated L/B ratios published to date. |
