The PEAXACT Viewer is a feature-reduced but completely free version of the PEAXACT Desktop App for interactive viewing of UV/VIS/IR/Raman/NMR spectra and models. PEAXACT Viewer offers more professional spectra visualization than most spectrometer measurement programs and hence is a popular replacement on spectrometer PCs.
