I need to quantify amino groups on the suface of treated PTFE.IR spectroscopy in the region of 1100 to 1800 nm shows the peak in 1400 nm which seems to be relavant to first overton N-H or O-H stretching bands.(our system works in this range of wavelenght-1100 to 1800 nm).How I can distinguish between the first overton N-H and O-H stretching bands to see whether or not this peak is relavant to N-H?
hi,
OH groups can be derived by gazeous treatment by SF4 or NO so as to deconvolute the overall absorption band.

Via polarized measurements in mid-IR and deuthero exchange techniques.
Hi,
Probably it is better to apply selective deuterium exchange, but you can also try to find if someone studied analoguous sistems to make an analogy, as can be done in corresponding MIR studies.
