Confidence votes 228. Infrared spectroscopy, or IR spectroscopy, is a method of spectroscopy used by organic chemists to help determine the structure of an unknown molecule. An IR spectrum will have peaks based on how much light was visible when shone through different parts of the molecule.
Infrared thermography is the technique of converting infrared energy (radiant heat) into an image that a person can see and understand. We ordinarily see in visible light. We can compare infrared to visible light-they are not the same, but they are analogous.he electronics in the camera convert the light energy that enters the lens into a video signal, and displays that signal on a monitor or TV. You see shapes, colors, textures, shadows, and reflective surfaces in the image as a result of the camera's ability to capture light.
