Hello!

How H-bonds effect on Raman spectra? Can we determine are there H-bonds in molecule with Raman spectra?

Is this a homework question?

Is this a homework question?

Yes, I'm studying english language, and one of the task was to ask a question at this forum.

 

However i would be very grateful if you recommend me some references (=

Ok. So I cannot answer your question - it is too advanced for me. But I can give you a few hints on the wording

 

How do H-bonds effect a Raman Spectrum? Can we determine if there are H-bonds in a molecule using Raman Spectroscopy?

The answer is yes, if you have a good enough spectrometer. Hydrogen bonding changes the bond length of the -O-H bond, thus changes the energy required to vibrate the bond (stretch). The shifts are usually <20cm^-1, so the spectrometer needs to have good resolution (Raman spectral resolution is typically poorer than IR). Another roadblock is that the OH stretching mode is very weak in Raman (that's why you can do Raman in aqueous solutions!). Sensitivity/Laser power will be an important factor. Personally, I'd go IR over Raman for this kind of information.
