Rotation of Molecules and Nuclear Spin Relaxation
TL;DR: In this article, a theory is needed which links the time constants of nuclear spin relaxation to the correlation functions describing the rotational motion, and a considerable part of this volume is devoted to this goal.

Density and temperature effects on the molecular reorientation and vibrational relaxation in liquid methyl iodide
TL;DR: In this paper, the reorientational correlation function for liquid methyl iodide has been measured by analysis of the Raman 526 cm−1 ν3 (a1) band as a function of pressure up to 2.5 kbar within the temperature range 0 to 90°C.

NMR Studies of the Rotational Diffusion of Symmetric Top Molecules in Liquids
TL;DR: In this article, temperature-dependent nuclear magnetic resonance relaxation times of quadrupolar nuclei in several symmetric top molecules (as neat liquids) are reported, and the success of the hydrodynamic calculation, the agreement with all available reorientational rates determined by dielectric relaxation, and semiquantitative "χ test" are used to confirm that these motions are indeed in the diffusion limit.
