I am trying to identify the components in a face mask. I observe the presence of polyethylene but I also see a C=O vibration at 1718. The spectral library is saying I have polyethylene, terephthalate but I'm not convinced. Is there some way I can say defininitively if terephthalate is present?
I don't see "benzene finger" in the spectrum either which would be found around 1800. I also don't see CH3 at 1375 nor do I see CH3 vibrations.
