Based on the activation energy (E (a)) and correlation time (tau(c)), we believe that the Schiff base derivatives perform a molecular tumbling motion.eninfo:eu-repo/semantics/closedAccessNmrSchiff BaseT-1 And T-2 Relaxation TimeActivation EnergyCorrelation TimeArticle826905909WOS:0003687171000032-s2.0-8495455796410.1007/s10812-016-0202-8Q4Q4
