Mate, you literally saved me. I have a Mac and all those spectra software that the cool kids have don't run on OS. Guess I can delete the virtual machine I downloaded to trick my Mac into running windows 10..
Hi, Sorry for troubling , I have a question about the FTIR data format, I got some datasets of FTIR data. But the sampling frequency is different from each others. Like yours, you have around 1870 sample collection points here. But some dataset didn't get the same number of sampling points. Best regards. Thanks
I mistakenly saved the FTIR data inf0rm of text. Copying to excel, the data for the x and y fall in one cell. Is it possible to change the data into two columns for plotting in excel.
One interesting aspect of the FFT when applying it to slow environmental datasets: The key to getting better resolution from the Fourier when you are limited to a fixed number of data points is to decrease the sample frequency (and thus increase the overall sampling time) We released a video demonstrating that optimization using Excel's Fourier transform to derive a tidal frequency spectrum: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0VzX-3erjPI.html
Oh boy... I totally appreciate you effort to plot spectra within Excel, but it is so painful to watch this annoyingly slow and cumbersome process. What about using Spectragryph, the free optical spectroscopy software and do the same tasks within seconds? There, you just drop your csv file and get an instant plot with proper layout, zoom and scale by using mouse and place the graphics into Word with one more click! Just my 50 cents.
