NOTE
1. Resolution and wavenumber accuracy of the FTIR are determined by the wavenumber interval of
spectral data. Since the maximum data interval of IRAffinity-1 is 0.25 cm
−1
, the peak position can be
read at an accuracy of ±0.125 cm
−1
. In case of the asymmetric peak, however, the accuracy for reading
the peak position should be ±0.25 cm
−1
.
2. The calculation of wavenumber accuracy based on the wavelength of the He-Ne laser is ±0.01 cm
−1
.
