Explain working of double beam ir spectrophotometer

Sure! A double beam IR spectrophotometer is a special machine that helps scientists study the different chemicals in a sample by shining light through it. It works by splitting the light into two beams – one that goes through the sample and one that doesn’t. Then, it measures how much light is absorbed by the sample at different wavelengths. This helps scientists figure out what chemicals are in the sample and how much of each one is present. For example, if you imagine shining a flashlight through a colored piece of paper, some colors would shine through while others would be absorbed by the paper. The IR spectrophotometer works in a similar way, but with invisible infrared light instead of visible light. One cool fact about IR spectrophotometers is that they are often used in forensic science to analyze evidence like fibers or drugs found at a crime scene. I hope this helps you understand how a double beam IR spectrophotometer works!
