The use of IR individual scaling factors (ISF) for the correction of DFT‐calculated frequencies, and its effect on IR and VCD similarity functions, has been evaluated using (+)‐(R)‐3‐methylcyclopentanone as a probe molecule. Contrary to using a single scaling factor to improve spectra matching, this approach sequentially searches for the optimal scaling factor for each calculated transition using...
The minimum chemical modification that can be incorporated into an organic molecule is the replacement of a hydrogen atom for a deuterium atom. This change is not altering the pharmacological properties of a molecule, although it provides the possibility of making specific spectroscopic evaluations. Thus, in the present study, we explore how a stereogenic center is influenced by such an isotopic labeling...
