    • There is some debate over this interpretation. In some older reports the -120°C phase transition is interpreted as the glass transition.

    • This intensity ratio was chosen since it visualizes the changes of the red part of the spectrum.

    • For LDPE the optimal intensity ratio (1505/1530) was found to be slightly different from the ratio used for i-PP. For i-PP the major changes were in the red part of the spectrum while for LDPE a notable decrease in intensity in the blue part of the spectrum was also found.
