Homework Answers
The advantages of Raman spectroscopy over IR spectroscopy are 1. Water shows weak band on Raman while intense band in IR.So we can easily use water as solvent in Raman. 2.Sampling is easy and less time consuming in RAMAN. 3.For Raman during vibration the change in dipole moment not needed like it needed in IR. 4.Raman spectroscopy is less time consuming. 5.Raman spectroscopy does not need a reference light path. 6. Remote sampling can be used.
