Mathematical Chemistry, Theoretical Chemistry, Computational Chemistry, etc

I am not so sure that you have got the definition of mathematical chemistry and its relationship to theoretical and computational chemistry exactly right. It tends to be used in a very restricted sense covering such direct mathematical ideas as graph theory and so on. The contents of the Journal of Mathematical Chemistry are very restricted. I do not think mathematical modeling is normally considered as part of mathematical chemistry. Your edit to Computational chemistry - "Computational chemistry uses the results of theoretical chemistry, in particular, its branch mathematical chemistry" is not, I think really correct. The mathematics of the various methods of computational chemistry are important, but they are not considered, as far as I can see, as mathematical chemistry. I think there are similar problems with your edit to mathematical chemistry. What do you think?
