![]() This confers a significant advantage over a dispersive spectrometer, which measures intensity over a narrow range of wavelengths at a time. This simultaneously collects high-spectral-resolution data over a wide spectral range. It is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid or gas. The frequency range are measured as wave numbers typically over the range 4000 – 600 cm -1. This absorption corresponds specifically to the bonds present in the molecule. : 50000:1 peak to peak 4 cm -1 resolution for a one minute measurement.įourier Transform Infrared Spectroscopy relies on the fact that the most molecules absorb light in the infra-red region of the electromagnetic spectrum.
