dc.description.abstractSpin-lattice (T-1) and spin-spin (T-2) relaxation times of seven peaks in dibenzo diaza 18-crown-6 ether derivative were measured at 300K with a Bruker 400 MHz NMR spectrometer. An equation was derived for correlation time tau from the ratio of the (1/T-1)/2(1/ T-2) using relaxation formulas pertaining to dipolar interactions. The correlation time was calculated from the equation for each peak using experimental data for (1/T-1)/2(1/T-2) ratio. The estimated tau values ranged from 0.7 ns to 2 ns. The similarity of T values of the peaks belonging to the different parts of the molecule suggested that overall molecular tumbling may be responsible for relaxation mechanism of all the groups.
