Summary:Biological and chemical materials often contain many molecular bonds that connect carbon (C) hydrogen (H) atoms. These bonds covalently share electrons that can be optically activated by light. The incident light interaction with the C-H molecular bond spectrally shifts of the incident light proportional to the vibrational, or more precisely polarizability, constant of the electrons that bind the C-H atoms. This process is called Raman scattering. For C-H, C-H2 and C-H3 bonding schemes, the spectral shift is approximately 3000 cm-1 lower in energy from the incident light energy. Using this fundamental spectral shift coupled with optical microscopy, the ability to detect materials that possess C-Hx (where x=1, 2 or 3) is possible.
