Determination of phase transitions in Y-shaped, branched alkane, C120H241CH(C195H391)C119H23 using Raman spectroscopy
Open Access
|Jan 2011Abstract
Raman spectroscopy has been used to identify solid – solid phase transitions in the symmetrically branched alkane, C120H241CH(C195H391)C119H23 during real-time heating. The vibrational modes in the region from 1700 to 200 cm-1 were studied. A single phase transition was identified at 87°C ± 5°C in this alkane based on the changes in the band intensities. It was revealed that the crystalline bands show subtle changes whereas the disorder bands show the most significant changes at this transition.
