Research output: Contribution to journalArticlepeer-review


The depolarized Rayleigh spectrum from pyrimidine has been obtained from 296K to 395K. The spectra do not display a shear wave dip at zero frequency due to translation-rotation coupling. The Stokes - Einstein - Debye plot of the reorientation time versus viscosity/temperature displays a slightly non-linear relation. The light scattering orientation pair correlation factor obtained by comparing the depolarized Rayleigh reorientation to the single particle time from NMR for pyrimidine is 2.3. This value is compared to other azobenzenes.
