Abstract
Raman spectroscopy has been used to identify solid – solid phase transitions in
the symmetrically branched alkane, C120H241CH(C195H391)C119H239 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.
