text: The FT-IR spectra were recorded using a Nicolet 170SX or a JASCO FT/IR-410 spectrometer. For spectra recorded in the Nicolet spectrometer, the data were stored at intervals of 0.5 cm in the 4,000 – 2,000 cm region and of 0.25 cm in the 2,000 – 400 cm region and the spectral resolution was 0.25 cm. For spectra recorded in the JASCO spectrometer, the resolution as well as the intervals was 0.5 cm. Samples from solids were prepared using the KBr disc or the Nujol paste methods, samples from liquids were prepared with the liquid film method. This collections contains ca 54,100 spectra and is being updated.
