Hey all

Just going through a computational chemistry paper and i noticed the following sentence.

"Hence, one can view the sequence of atom types, C1 to C21, as a quasicontinuous deformation of a methane carbon atom to a guanidinic carbon atom"

Now there are not many references on the web to gaunidinic carbon atoms, other than guanidine

found:
http://en.wikipedia.org/wiki/Guanidine

What does that author mean by a guanidinic carbon atom?

Cheers

I expect it just means the C atom of the guanidine group of the compound in question, it's just a way of expressing which atom you're talking about - instead of giving a number you can quote the functional group (if it is unambiguous).

It's the same as referring to "the aldehydic proton" in an nmr, that kind of thing.

What's the article? If it's online I probably have access and can look at it for you if the above doesn't make sense in the context of the paper.

Cheers for the reply Dan

What you said make perfect sense, especially in the context of the paper, which is a comparison between atom types found in different force fields.

many thanks
