I worked with gaussian to simulate vibrational IR and Raman spectra. For that purpose, I scaled the vibrational frequencies from my gaussian calculation with the scaling factors from this website:
I am writing my bachelor thesis now and wonder where the website found the scaling factors. On the bottom of the page is a reference to a paper.
Some of the above values were taken from
A.P. Scott, L. Radom, Harmonic Vibrational Frequencies: An Evaluation of Hartree-Fock, Moller-Plesset, Quadratic Configuration Interaction, Density Functional Theory and Semiempirical Scale Factors, J. Phys. Chem. 100, 16502, 1996
In this table many scale factors were assumed to be the same for different basis sets and similar methods.
I read the paper and did not find the scale factors I used in my work. For my thesis, I need papers to cite, so I want to ask, how did they assume the scale factors, or where did they find the other scale factors?
