Raman Spectroscopy

IR Spectroscopy 

   · Change in polarizability

     (charge separation, form instantaneous dipoles) 

     (induced dipole moment)

   · Able to use aqueous solutions

    · Change in dipole moment

     (the molecules should have two poles-permanent)

     ex) HCl : One positive hydrogen and one negative chloring 

    · Cannot use with aqueous solutions
