Abstract

The spin-lattice relaxation time T (1) and the spin-spin relaxation time T (2) of two Schiff base derivatives, N,N'-ethylenebis(salicylidene)-1,2-diaminoethane (H2L1) and N,N'-ethylenebis (salicylidene)-1,3-diaminopropane (H2L2), in DMSO-d(6) solvent were studied as a function of temperature in the range of 20-50A degrees C using a Bruker Avance 400.132 MHz H-1 NMR spectrometer. Based on the activation energy (E (a)) and correlation time (tau(c)), we believe that the Schiff base derivatives perform a molecular tumbling motion.
