This paper continues an effort which was initiated  to simplify the identification of drugs and common organic poisons from their ultraviolet (UV) spectra. To accomplish this end, compounds have been placed in groups according to similarities in the molecular structure. More specifically, compounds with the same unsaturated, conjugated parts of the molecule have been placed in the same group. Compounds in each group therefore have similar UV absorption characteristics and show similar pH and solvent effects. Sixteen groups were studied in Part I . This paper will deal with 13 structural groups consisting primarily of drugs and drug precursors presently available legally or illegally in the United States. Practical reviews dealing with approaches to interpretation of UV data are found in Refs 1-6. Theoretical aspects of spectrophotometry are covered in Refs 7–10. References containing a substantial number of illustrated spectra include 11–16.
