摘要：
The spin–lattice relaxation time T1 and the spin–spin relaxation time T2 of two Schiff base derivatives, N,N'-ethylenebis(salicylidene)-1,2-diaminoethane (H2L1) and N,N’-ethylenebis (salicylidene)-1,3-diaminopropane (H2L2), in DMSO-d6 solvent were studied as a function of temperature in the range of 20–50°C using a Bruker Avance 400.132 MHz 1H NMR spectrometer. Based on the activation energy (Ea) and correlation time (τc), we believe that the Schiff base derivatives perform a molecular tumbling motion.
