Abstract
شاخص هاي توپولوژيكي مقادير عددي مي باشند كه جهت بررسي همبستگي ساختار شيميايي باخواص فيزيكي متفاوت، واكنش پذيري شيميايي يا فعاليت بيولوژيكي بكار مي روند. نظريه گراف يك زمين بازي لذت بخش جهت اكتشاف تكنيك هاي اثبات رياضيات گسسته است. يكي از شاخص هاي مفيد جهت بررسي ارتباط كمي ساختار-خاصيت شاخص رانديك است. در اين تحقيق به مطالعه ارتباط كمي شاخص هاي رانديك، بالابان، سگد و عدد هراري با آنتالپي سوختن به حالت مايع ( )، آنتالپي تبخير ( )،آنتالپي تشكيل ( ) و آنتالپي تصعيد ( ) مونو كربوكسيليك اسيد هاي (C2-C20) پرداخته و سپس شاخص هاي مناسب براي بررسي ارتباط كمي ساختار- خاصيت ارايه شده است.
Abstract
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 Randicʹ
index. In this study is represented the relationship between the Randicʹ, Balaban and Szeged
indices and Harary numbers to the enthalpies of combustion (
?
C H ? liquid), enthalpies of
vaporization (
?
vap H ? gas), enthalpies of formation (
?
f
H ? liquid) and enthalpies of sublimation
(
?
sub H ? ) of monocarboxylic acids (C2?C20) are established, and then, some useful topological
indices for examination of the structure- property relationship are presented.
