can anyone explain what is d band and g band in the Raman spectrum of graphene?
It seems like physicists don't care about Raman Spectroscopy. I asked last time if someone could suggest a good book on Raman spec , but there was no single reply.
Anyway,check the answers fro your question here: http://http://rsta.royalsocietypublishing.org/content/366/1863/231.full" [Broken]
They are different ways that the carbon atoms shake, I was trying to find a good picture online but couldn't quickly. But Raman spectrum obviously is a test of the phonon vibrational modes. There are different ways something can resonantly vibrate and there are different energies associated with the different vibrations.
I have a forest of carbon nanotubes. They are vertically aligned, like this picture:
I wonder if it is possible to get Raman spectra from the
b) about 50nm from below the surface
of the nanotubes?
As far as I know, Raman spectroscopy is a surface analyzing method. For carbon nanotubes, I assume it should be the same. Now, I wonder if I can get Raman data for the two different positions of the nanotubes mentioned above.
Thank you very much.

I am working with Raman spectroscopy but I didn't enter for a long time on this forum.
Tzontonel do you think we can share some information regarding Raman?
If yes this is my email adress and I will be happy to discuss about some problems which I have using Raman email@example.com If you want send me an email with the subject Raman
By the way, two scientists from Univ of Manchester get the Nobel prize for graphene characterization and separation:) I don't know if they used Raman
this was for toex
I am really interrested in Raman spectrometry because is one of my subject for my PhD.

and I started a new project: http://ramandata.sourceforge.net/" [Broken] (I'm a child in JAVA, so this is another story ...). By the way, if you have time and a internet connection you can make and find anything. Just put a question or maybe you know - Google is you best friend.
Later edit: where are you from? what type of spectrograph do you use? Organic? or Inorganic?
