The 400 MHz 'H and 13C NMR parameters of 15 monoand polybrominated biphenyls were determined and compared with those of the corresponding chlorinated biphenyls.

Spinosin, a C-glycoside flavonoid, was isolated from the plant Desmodium tortuosum (Sw.) DC. The 1 H and 13 C NMR data acquired at room temperature exhibited doubling of signals, suggesting the presence of two rotamers in solution. Variable-temperature 1 H NMR experiments confirmed this hypothesis.
