  • We derived a simple reduced form from the exact solution of the mixed magnetic and quadrupolar nuclear spin--lattice relaxation function at the central transition line of a quadrupole-split NMR spectrum for the nuclear spin $I$ = 3/2. The reduced form of the exact solution could be extended to include inhomogeneous relaxation effects. From the application of the reduced form to the $^{63}$Cu nuclear spin--lattice relaxation curves in the high-$T_\mathrm{c}$ superconductors of $^{63}$Cu-enriched triple-layer HgBa$_2$Ca$_2$Cu$_3$O$_{8+δ}$, we estimated the predominant magnetic relaxation rate $^{63}W_M$ and the upper limit of a weak nuclear electric quadrupole spin--lattice relaxation rate $^{63}W_Q$.
