In the limit of complete bonding, hard‐sphere polyatomic molecules are formed. As well as the general expressions for polyatomic molecules and their mixtures, the equation of state of hard‐sphere chain molecules, which are simple models of homologous series such as the alkane...
104K Just as the Lewis dot structure can visualize molecules, it can also visualize polyatomic ions, which are ions containing multiple atoms. Explore the actions of polyatomic ions and learn how to visualize them through the lens of the Lewis dot structure. Related...
Molecules that are composed of atoms of more than one type is called a polyatomic molecule. The molecular formula consists of chemical symbols for all the constituent atoms, where the number of atoms of each type is written as subscripts following their respective symbols....
In this paper two semi-empirical models are presented. By the one model the electron impact ionization cross sections of polyatomic molecules can be estima... M Bobeldijk,WJVD Zande,PG Kistemaker - 《Chemical Physics》 被引量: 150发表: 1994年 Studies of the intramolecular dynamics of model ...

Achieving similar temperatures for polyatomic molecules, however, remains challenging. Since polyatomic molecules are characterized by multiple degrees of freedom and have correspondingly more complex structures, it is far from obvious whether there exists polyatomic molecules that have the nearly-closed optic...
The quenching rate constantskqfor the following rare gases and small molecules (He, Ar, Xe, H2, D2, N2, O2, F2, Cl2, HF, CO, CO2, CH4, CHF3, CF4, NO2F, SOF4, SF6, and UF6) are reported in units of cm3molecule1s1for both the 1.0 and 2.3 μm excited electronic states of ...
We establish a discrete lattice dynamics model and its continuum limits for nonlocal constitutive behavior of polyatomic cyclically closed linear chains being formed by periodically repeated unit cells (molecules), each consisting of n 鈮 1 atoms which all are of different species, e.g., ...
Which of the fundamental forces is most important in determining the nature of chemical reactions between atoms and molecules? Both ethene and ethyne are often called by their more common names. Give the common names, and draw the structural formula for each...
Use the Lewis formulas to represent the covalent molecules formed by these pairs of elements. Write only structures that satisfy the octet rule. (a) S and Cl; (b) As and F; (c) I and Cl; (d) Se and Cl. Use the Lewis formulas to represent the covalent molecules formed by these ...
