Preface StandardReferenceMaterials"(SRMs)asdefinedbytheNationalInstituteofStandardsand Technology(NIST)arewell-characterizedmaterials,producedinquantityandcertifiedforone Polystyrene film has long been employed as convenient standard for the calibration of infrared spectrometers, especially in the v(CH) and fingerprint regions, because of its innumerable, strong, sharp, well-resolved peaks. Unfortunately, these films are not universally useful; in particular, there are no suitable calibration peaks around 2000
