«Mathematical chemistry concerns itself primarly with the novel application of mathematical methods in the chemical realm. The novelty is commonly expressed in one of thwo ways, viz. (i) the development of new chemical theory, and (ii) the development of new mathematical approaches which enable us to gain insights into or to solve problems of chemical interest.» Rouvray D. H., Editorial Foreword (недоступная ссылка), Journal of Mathematical Chemistry, Volume 1, Number 1, March, 1987.
