Why Raman spectra for ferroelectric ceramics show intense response at lower frequency?

What information can be had from raman at higher wavenumber?

i have recorded raman spectra of strontium oxide thin film. the spectra were recorded in the range 400 to 4000 cm-1. i have reference to peaks upto 1000cm-1. but i couldn't find literature for...

How can I find a Raman spectrum wavenumber corresponding to what compound?

I have several Raman spectra with very distinct peaks at certain wavenumbers, such as 277, 359, 466, 583, 623, 686, and 795cm-1. How can I identify them to what compound(s)? The RRUFF and others...

How can I simulate the optical absorption spectrum of a biomaterial (like DNA or protein) in COMSOL?

I need to simulate the optical properties of a biomaterial, namely DNA, in COMSOL. Basically I need to simulate the IR absorption spectrum of a cylinder filled with a 'concentration' of DNA. I am...

How to get better phase shift in C-V curves for ferroelectric devices?

I tried to sweep my ferroelectric devices from -2V to 2V and then from 2V to -2V and The two hysteresis peaks are off by several microFarads. Should i increase bias voltage? I am doing these...

Could we interpret the intensity of the peaks of the FTIR spectrum correlating to the concentration of some compound?

If we analyze the extract of two plants from the same species (for example) and there are very similarities between the two IR spectra except for the intensity of one peak at the same wavenumber....

Hi Shilpi,

I am not sure I understand your question. What do you mean by intense response ? Intense with respect to what ? The way I see it Raman spectroscopy is a technique especially developed to identify low frequency modes in polar or polarizable molecules.

(https://en.wikipedia.org/wiki/Raman_spectroscopy)

That being said, I would be able to give a more detailed answer if you could be more specific with the details or provide some background information.

I hope it helps.

Regards
