Animated Vibrational Modes of Triatomic Molecules

animations, infrared/Raman spectroscopy, Resources by Format, spectroscopy, spectroscopy, Techniques
When infrared light is absorbed by molecules, it causes them to vibrate. This paper includes computer animations of molecules vibrating. The animations show two simple molecules (sulfur dioxide and carbon dioxide) vibrating in different modes. In the examples, animated movies show the fundamental vibrational modes of sulfur dioxide and carbon dioxide. Similarly, animations show the composite…

How an Interferogram is Produced – An Animated Explanation

animations, basics, infrared/Raman spectroscopy, instrumentation, Resources by Format, spectroscopy, spectroscopy, Techniques
This animated tutorial explains the principles behind the operation of the interferometer in an FTIR spectrometer.  The tutorial examples start from a single wavelength so that students can begin with an easier example. After that, the examples explain the superposition of multiple wavelengths. Finally, the tutorial explains the connection between an interferogram and a frequency domain…
