Temperature effect on molecular rotational dynamics of NMBHC-2-one in ethanol and octanol solvents.

Rotational reorientation dynamics of NMBHC-2-One has been studied in ethanol and octanol solvents by varying temperature using picosecond time-resolved spectroscopy. Experimental rotational reorientation time shows NMBHC-2-One experiences higher friction in octanol than ethanol. Qualitative analysis using SED, GW, and DKS mechanical frictions theories has been performed. The theoretical measured reorientation times of NMBHC-2-One fails to explain the observed experimental values, it enables us to test dielectric friction theories. [ABSTRACT FROM AUTHOR]
