The analysis of A 2 B 2  spectra, especially the assignment of lines is further treated. Explicit expressions for the A 4  spectrum as a limiting case of an A 2 B 2  spectrum have been calculated and are listed. The observation of multiple quantum transitions in an A 2 B 2  system is reported. Spin coupling and shielding parameters are given for 30 para-disubstituted benzenes and some other compounds. For pyrrole an improved set of spin coupling parameters could be obtained, making use of the information from C 13  satellites. Substituent effects for the meta spin coupling in paradisubstituted benzenes are derived. A correlation with the electronegativity of the substituent is demonstrated and some arguments for a theoretical treatment are discussed.
