"Together these complementary perspectives provide a deeper understanding of the localization of electrons and bonds, the origins of chemical interaction and reactivity behavior, the interaction between the geometric and electronic structure of molecules, etc. In the opening two parts the basic principles and techniques of the contemporary computational and conceptual quantum chemistry are presented, within both the wave-function and electron-density theories. This background material is followed by a discussion of chemical concepts, including stages of the bond-formation processes, chemical valence and bond-multiplicity indices, the hardness/softness descriptors of molecules and reactants, and general chemical reactivity/stability principles. The insights from Information theory, the basic elements of which are briefly introduced, including the entropic origins and orbital communication theory of the chemical bond, are the subject of part IV. The importance of the non-additive (interference) information tools in exploring patterns of chemical bonds and their covalent and ionic components will be emphasized."

"Berat molekul polimer pada umumnya tidak seragam, terdiri dari polimer dengan berat molekul rendah, sedang sampai tinggi, dan jika disusun dari yang paling rendah sampai yang palig tinggi akan merupakan suatu sebaran atau distribusi berat molekul. Pengukuran berat molekul polimer tidak cukup ditentukan hanya oleh berat molekul rata-rata tetapi juga oleh distribusi berat molekulnya.Tulisan ini bertujuan mengungkapkan hubungan antara istilah-istilah dalam pengukran berat molekul polimer dengan istilah-istilah statistika seperti varian dan koefisien variasi."
