Is it possible to "fit" a series of theoretical spectra to an experimental spectrum?

I have a series of computed IR spectra for a variety of gas-phase conformations of a molecule (calculated through Gaussian) in addition to the experimental spectra obtained using IRMPD-MS...

How do I format the PES scan of a proton-transfer reaction in G09?

Attached is an image of two molecules for which I would like to carry PES calculations- as a proton is migrated from one molecule to the other. I've been trying the attached input in Gaussian09...

Why are some IRMPD data moldeled at 300K instead of 298.15K?

I've noticed that some IRMPD spectroscopy papers (particularly gas-phase biomolecules) have computational data that were carried out at 300K instead of the standard 298.15K. Why is that? *Some...

Can peptides without Tyr, Trp, Phe, or His be analyzed by UV-HPLC?

I have a series of N-acetylated peptides in the form of Ac-AnK-OH, where n = 2-6. They are of decent purity ~80% but still have some residual TFA and smaller contaminants that make it difficult...
