32. Which of the following statements concerning Raman is INCORRECT?
(A) Raman scattering arises from changes in molecular polarizability during vibrational motion.
(B) The Stokes signal arises from inelastic photon scattering, producing a lower-energy shift relative to the excitation light.
(C) A bandpass filter is used to reject the intense Rayleigh-scattered light at the laser wavelength, allowing Raman-shifted signals to be detected.
(D) Raman scattering from Raman-active analytes increases with decreasing excitation wavelength.
(E) Raman scattering from Raman-active analytes is enhanced in the presence of silver nanoparticles due to surface-enhanced Raman scattering.
