can anyone explain what is d band and g band in the Raman spectrum of graphene?
Can You Share Information on Raman Spectroscopy for Graphene?
In summary, the conversation discusses Raman spectroscopy and its application in studying graphene. The d band and g band in the Raman spectrum of graphene are different ways that the carbon atoms vibrate. The conversation also mentions a book recommendation for Raman spectroscopy and the use of Raman in characterizing and separating graphene, as well as the possibility of sharing information and resources on the topic. One participant mentions their interest and work with Raman spectroscopy and their project for creating a database of Raman data.

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"

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.

Hi all,
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
a) surface
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 taranu_a@yahoo.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

http://rdrs.uaic.ro" - Romanian Database of Raman Spectroscopy [...]
and I started a new project: http://ramandata.sourceforge.net/" (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?

Related to Can You Share Information on Raman Spectroscopy for Graphene?
1. What is a Raman spectrum?
A Raman spectrum is a type of spectroscopic technique used to study the vibrational modes of a material. It involves shining a laser on a sample and measuring the scattered light, which contains information about the molecular vibrations of the material.
2. What is Graphene?
Graphene is a two-dimensional material made of a single layer of carbon atoms arranged in a hexagonal lattice. It is known for its unique properties, such as high strength, electrical conductivity, and flexibility.
3. How is Raman spectroscopy used to study Graphene?
Raman spectroscopy is commonly used to characterize the vibrational modes of Graphene and provide information about its structural properties. It can also be used to identify defects and doping in Graphene samples.
4. What types of information can be obtained from a Raman spectrum of Graphene?
A Raman spectrum of Graphene can provide information about its structural properties, such as the number of layers, defects, and doping levels. It can also give insight into the electronic and mechanical properties of the material.
5. What are the advantages of using Raman spectroscopy to study Graphene?
Raman spectroscopy is a non-destructive, fast, and versatile technique that can provide valuable information about the properties of Graphene. It also requires minimal sample preparation and can be performed on samples in various forms, such as powders, films, and suspensions.
