Hi, FTIR people, I am a graduate student and just begin on my project. I have a question regarding the curve-fiiting FTIR spectra. What I need to do is: 1. Inverted 2nd-derviate spectra; 2. Have a curve-fitting; 3. Find out the peaks area correspond several major peaks. I wonder if any software come with the FTIR will work for this purpose? If not, does anyone know any other software will works? Any suggestion is welcome. BTW, the FTIR i am using now is ruker Vector 33 FTIR Spectrometer Running Opus Spectroscopic Software. Don Zhao | ||

Don, Your message repeated twice because you need to wait for the system to respond as it sends the emails to everyone on the list. If you hit the send button too quickly, it will send the message again. With respect to your curve-fitting project, you have to be careful. I and another person tried curve-fitting of spectral data a number of years ago (that makes me sound ancient, right?). Anyway, we found you have to carefully set limits on how many curves you combine as otherwise the system will keep trying to add more curves with little or no improvement. I don't know if others have tried to fit whole curves, there probably are many examples in the literature now. Bruce |
