First of all, sorry about my english.
Secondly, I would like to ask you, FTIR expert people, about a doubt in my work. I study the degradation of some polymers in processing and I obtained some FTIR data with absorption in 1640 cm-1 and 1720 cm-1. I would like to compare these two chemical groups quantitatively to see which is generated preferentially in function of the variation of temperature of the process. The doubt is about the molar absorptivity:
1. Where can I find the values, roughly, for these two chemical groups?
2. Can I do this comparison with my FTIR data? The major part of the table data I found is about ultraviolet and almost nothing about FTIR.
That´s it guys! Sorry if I am so dummy..
Thanks!
Walter
