## Abstract The application of selective population inversion (SPI) to the assignment of ^13^C resonances and to the determination of the relative sign of ^13^Cο£Ώ^1^H coupling constants is demonstrated for 1βphenylβ1,2βdibromoβ2βnitroethane. A negative sign for the geminal Cβ2ο£ΏHβ1 coupling constant
## Abstract The identification and complete ^13^C and ^1^H assignment of a sample of oligomycin A is described. ^13^C multiplicities were determined by the INEPT method; assignments were made by comparison of heteronuclear ^13^Cβ^1^H chemical shift correlation, homonuclear COSY and homonuclear rela
