Dispersive Infrared Spectrophotometer. a grating … A Fourier Transform InfraRed (FT-IR) Spectrometer is an instrument which acquires broadband Near InfraRed (NIR) to Far InfraRed (FIR) spectra. Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light. IR spectra are acquired on a special instrument, called an IR spectrometer. IR is used both to … Spectroscopy - Spectroscopy - Infrared spectroscopy: This technique covers the region of the electromagnetic spectrum between the visible (wavelength of 800 nanometres) and the short-wavelength microwave (0.3 millimetre). This is a double beam scanning IR instrument that makes use of a diffraction grating in a monochromator to disperse the different …
The spectra …
The simplest instrument for IR absorption spectroscopy is a filter photometer similar to that shown in Figure \(\PageIndex{1}\) for UV/Vis absorption. Unlike a dispersive instrument, i.e. Filter Photometer. Instrument Designs for Infrared Adsorption. It covers a range of techniques, mostly based on absorption spectroscopy… Infra-red Instrumentation. Infrared Spectroscopy: Theory An important tool of the organic chemist is Infrared Spectroscopy, or IR.
