University of Kashan Iranian Journal of Mathematical Chemistry 2228-6489 6 1 2015 03 01 Relationship Between Topological Indices and Thermodynamic Properties and of the Monocarboxylic Acids Applications in QSPR 15 28 8944 10.22052/ijmc.2015.8944 EN F. Shafiei Department of Chemistry, Science Faculty, Arak Branch, Islamic Azad University, Arak, Iran Journal Article 2014 10 23 Topological indices are the numerical value associated with chemical constitution purporting for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. Graph theory is a delightful playground for the exploration of proof techniques in Discrete Mathematics and its results have applications in many areas of sciences. One of the useful indices for examination of structure- property relationship is Randic' index. In this study is represented the relationship between the Randic', Balaban and Szeged indices and Harary numbers to the enthalpies of combustion ( liquid), enthalpies of vaporization( gas), enthalpies of formation ( liquid) and enthalpies of sublimation ( ) of monocarboxylic acids (C2- C20) are established, and then, some useful topological indices for examination of the structure- property relationship are presented. https://ijmc.kashanu.ac.ir/article_8944_42c0fe9fb5ea15ff42c016263779416c.pdf
