Figure 1: Example of an average Raman spectrum from a lung cancer cell (black) after baseline subtraction. The major spectral peaks and regions which correlate to the molecular vibrations collected from Raman scattering of DNA, lipids, and proteins are highlighted. (Note that the x-axis is in Raman shift which is defined in wavenumber (cm−1), the inverse of wavelength in centimeters).
