IR Spectra Replicated by PiFM Spectra
Agreement Between PiFM and Conventional IR 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 […] Read more
