Question

HINT: Resolution has the same meaning in FTIR spectroscopy as it does in other forms of spectroscopic analysis. The maximum retardation can be determined from the mirror travel, and the resolution is determined from the maximum retardation. The retardation interval is related to the range of wavenumbers (cm–1) that are examined in the spectra.

Answer the following questions regarding Fourier transform infrared spectroscopy: A) Which of the following correctly describes the term "resolution"? O The ability to distinguish closely spaced peaks. O The ability to collect simultaneous spectra rapidly O Reproducible measurements with a low relative standard deviation. O High signal-to-noise due to broad, overlapping peaks For a Fourier transform infrared spectrophotometer that contains a mirror that travels ± 2.4 cm; B) Calculate the maximum retardation and resolution of the instrument? Number Number Resolution cin cin C) For proper coverage of a spectral range(Av) of 215 to 2200 cm-1 at what retardation interval (Ö), in millimeters, does the interferogram need to be sampled? 0-1, at what retardation interval Number mim
