+    and :math:`140\,\text{K}`, and compared with the correlation functions reported by Grivet :cite:`grivetNMRRelaxationParameters2005`.
+    Our results show an excellent agreement with the results from Grivet, thus validating the
+    NMR formalism used here as well as the LJ system and parameters.
