Dibutyl Phthalate - an overview | ScienceDirect Topics

In the following example, the glass forming dibutyl phthalate (DBP), with a glass temperature T g =178 K, was investigated by NFS (sensitive to translational and rotational dynamics) and SRPAC (sensitive only to rotational dynamics) (Sergueev et al., 2003).Ferrocene was used as probe molecules. NFS spectroscopy is applicable as long as the Lamb-Möss factor f LM is greater than zero .
