Describe the variables, then summarize the overall shape of the spectrum, noting major peaks, troughs, and any notable regions where the intensity changes

"Raman spectra for bulk Ice XI compare intensity in arbitrary units with Raman shift from about 150 to 3,600 inverse centimeters. PBE-D2 harmonic, 25 kelvin TDEP, and 100 kelvin TDEP spectra show sharp peaks mainly between 2,500 and 3,300. The experimental 65 kelvin spectrum has a broader high-intensity region near 3,000 to 3,400 and smaller low-shift peaks."
