FTIR Transmission Spectra Databases

Our Transmission spectra were measured at the National Institute of Advanced Industrial Science and Technology in Japan (AIST) under strict controls.

  • The instruments were regularly maintained and calibrated
  • The quality of the spectra has been verified by expert spectroscopists
  • Fine chemical producers in Japan provided the high purity samples
  • The samples were checked using NMR and MS
  • The data input was checked through secondary verification
  • Samples were measured with KBr, Liquid Film or Nujol with a spectral range of 4000 cm-1 to 400 cm-1
