I’ve tried so many methods to use the Avogadro1.99.0 to open the VCD spectra,but it only can open the IR spectra and even not have the choice of VCD spectra,why???
I am not 100% sure but I believe that vibrational circular dichroism spectra are not available to be opened at this point. I know for a fact that if it isn’t then @ghutchis is working hard to get it implemented, but there are a lot of other small bugs and large QOL improvements that have to get done as well.
For now I recommend checking in the manual of whichever program you are using (I know ORCA has a utility program for plotting spectra) to see what they recommend!
Correct. I had a long list of features to get into 1.99 and CD / VCD spectra were behind other tasks.
Finishing up a variety of spectra types is on the list for the next release, naturally.
