Abstract: The 29Si and 13C NMR spectra of ten cyclodisilazane derivatives(R1=Me,ф;R2=Me,ф;R3=Me;X=Me,ф,OH、OSiMe3、Hand Cl) and nine related polymrfes(m=2,3,4,7 and 10)have been studied systematically. The effects of substituents X, R1 R2 and si-loxane chain length on chemcal shifts have also been discussed. The results show that there are (p-d)π interactions between N atom and three adjacent Si atoms in cyclodisilazanes.
