Molecular Absorption Measurements by FT/UV-Vis Spectrometry

Not Accessible

Your library or personal account may give you access


Fourier transform spectrometry in the UV-Vis region (FT/UV-Vis), because it is source shot-noise limited, has a signal-to-noise ratio (S/N) disadvantage in comparison to dispersive spectrometry, especially with dense spectra. At the expense of poorer S/N, FT/UV-Vis can be satisfactory for high-resolution measurements. However, low-resolution spectroscopic studies, such as molecular absorption measurements, are not expected to be performed advantageously by FT/UV-Vis. The broad, dense spectra with high intensity throughout a wide spectral range should show a significant S/N degradation, in comparison to results with dispersive spectrometry. To investigate these expectations, we have used a Michelson interferometer to obtain low-resolution molecular absorption spectra of polycyclic aromatic hydrocarbons (PAHs).
