systems can now produce IR light in the wavelength range 1.35−5 μm. This has, in turn, driven the development of novel action spectroscopies such as infrared resonance enhanced photodissociation (IR-REPD), which provides information on geometric structures of isolated, gas-phase metal ion−ligand complexes.

The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR radiation produced by the lamp is very close to the 4.26-micron absorption band of CO2. Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or "fingerprint" to identify the CO2 molecule.

For instance, light is absorbed by CO2 at 4.3 μm, within the IR band of the electromagnetic spectrum. The sensor measures the IR light directed at the CO2 gas. Other wavelengths are prevented from hitting the sensor via a NASA Technical Reports Server (NTRS) IR spectra of Cadmium red, light (CdS+CdSe) mixed with linseed oil .

let's look at some practice IR spectra so here we have three molecules a carboxylic acid and alcohol and an amine and below there's an IR spectrum of one of these molecules so let's figure out which molecule has this IR spectrum so we could draw a line around 1500 and ignore the stuff to the right and focus in on the diagnostic region and here is your double bond region and I don't see a
