Structural Dynamics of Chloromethanes through Computational Spectroscopy: Combining INS and DFT

open access: yesMolecules, 2022
In this work, the structural dynamics of the chloromethanes CCl4, CHCl3 and CH2Cl2 were evaluated through a computational spectroscopy approach by comparing experimental inelastic neutron scattering (INS) spectra with the corresponding simulated spectra ...
