How to correlate red- and blueshift in IR/Raman spectra and their intentisities to explain the structural phase transitions in molecular crystals?

In molecular crystals especially hydrogen bonded systems we often see red-/blue-shift in the IR/Raman spectra when they subjected to high pressure/temperature. When IR/Raman spectra show red- to...
