Abstract

In this paper, necessary and sufficient conditions are given for the existence of molecular graph(s) with the prescribed sequence m₁₁, m₁₂, m₁₄, m₂₂, m₂₄, m₄₄, where m_ij denotes the number of edges (bonds) connecting vertices (atoms) of degree i with vertices of degree j. The main result expressed as Theorem 1 covers the great variety of molecules with valencies 1, 2 and 4.

Keywords
