Abstract
C-13 CP/MAS NMR indicates that piperazine forms a hydrogen bond with the C7 -OH group of genistein. The hydroxyl proton is transferred to the piperazin e nitrogen atom. It is shown that the I-I*-S model of the polarization tran sfer in isolated spin clusters is also valid for quaternary carbon atoms. ( C) 2000 Elsevier Science B.V.
