Natasha Ingraham / Chemistry 112 / Laboratory 002 / Robin McCown / September 10, 2013 Pre-Lab Questions / Experiment #2 / Infrared Spectroscopy 1. The theory behind infrared spectroscopy is that since bonds between atoms are constantly in motion (molecular vibrations), photons of infrared radiation can be absorbed by bonds if they have the right energy. If the frequency of the IR radiation matches that of the vibrating bond it will be absorbed, increasing the amplitude of vibrations and thus kinetic energy of the molecule. It continues to explain that different bonds will absorb different frequencies of IR, making every piece unique. It is important to chemists and scientists because they utilize the theory with detectors; they can sense what wavelengths are hitting it and which aren’t. This creates an image (spectrum) that corresponds with what wavelengths passed and didn’t. A trained chemist could look at the generated spectrum and recognize their various compounds and functional groups.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
