IR Spectra Replicated by PiFM Spectra
PiFM spectra generally replicate conventional IR spectra recorded from bulk samples, shown in this example of polyethersulfone (PES). Occasionally, slight shifts in peak wavenumber and amplitude are observed in PiFM spectra, arising from the extreme sensitivity of PiFM to localized populations of molecules. One strength of the PiFM method is capturing the behavior of materials […] Read more
