FTIR of Polyetheyle
Posted: Thu Aug 29, 2013 7:15 pm
Hi,
I took a spectrum of a polyethylene sample and saw double peaks for the CH2 rock peak which i thought meant that it is HDPE.
However, the actual density was 0.914 g/mL. That means its LDPE. So why did I see double peaks for CH2 rock near 720cm-1??
Thanks,
