b) beset by difficulties in measuring relative intensities of bands from different samples, due to sample alignment, collection efficiency, laser power. c) Overcome by using internal standard. Applications of Raman Spectroscopy
Image of page 55
Application Raman spectroscopy is commonly used in chemistry, since vibrational information is specific to the chemical bonds and symmetry of molecules. Therefore, it provides a fingerprint by which the molecule can be identified. In solid-state physics, spontaneous Raman spectroscopy is used to, characterize materials, measure temperature, and find the crystallographic orientation of a sample

    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.
