Explain working of double beam ir spectrophotometer with its block diagram and its parts

Sure! Imagine you have a special machine called a double beam IR spectrophotometer. This machine helps scientists look at different substances to see what they are made of. It works by shining a special light through a sample and measuring how much light is absorbed. The machine has two beams of light – one that goes through the sample, and one that goes through a reference sample. By comparing the two beams, scientists can figure out what chemicals are in the sample. The block diagram of the spectrophotometer shows how the light goes through the sample and reference, and how the measurements are taken and analyzed. Some important parts of the spectrophotometer include the light source, sample holder, and detector. The light source sends out the light, the sample holder holds the sample, and the detector measures how much light is absorbed. A verifiable fact about IR spectrophotometers is that they are commonly used in chemistry labs to analyze compounds and identify unknown substances. Overall, the double beam IR spectrophotometer is a helpful tool for scientists to study the composition of different materials.
