The current e-book is an try to define a few, under no circumstances all, mathematical facets of contemporary natural chemistry. we've got concentrated our cognizance on topological, graph-theoretical and group-theoretical positive factors of natural chemistry, elements A, B and C. The e-book is directed to all these chemists who use, or who intend to take advantage of mathe­ matics of their paintings, and particularly to graduate scholars. the extent of our exposition is adjusted to the mathematical history of graduate scholars of chemistry and just some wisdom of uncomplicated algebra and calculus is needed from the readers of the ebook. a few much less famous. yet nonetheless common mathematical proof are accumulated in Appendices 1-4. This, although, doesn't suggest that the mathematical rigor and various tedious, yet invaluable technical information were kept away from. The authors' purpose was once to teach the reader not just how the result of mathematical chemistry glance, but additionally how they are often acquired. in line with this, half zero of the booklet includes a few chosen complicated subject matters which should still supply the reader the flavor of the modern examine in mathe­ matical natural chemistry. one of many authors (I.G.) used to be an Alexander von Humboldt fellow in 1985 whilst the most a part of the booklet used to be written. He gratefully recognizes the monetary aid of the Alexander von Humboldt starting place which enabled his remain on the Max-Planck-Institut fUr Strahlenchemie in M iilheim and the writing of this book.
