Raman spectroscopy

raman-spectometer

Introduction to Raman spectroscopy Raman spectroscopy was named in the honor of its inventor, C.V. Raman. Raman spectroscopy (RS) is a versatile method for analysis of a wide range of samples. It resolves most of limitations of other spectroscopic techniques. Continue reading
