溶液法测定极性分子的偶极矩(The dipole moment of a polar
molecule is determined by the solution method)
The dipole moment of a polar molecule is determined by the solution method
I. purpose and requirements
The dipole moment of ethyl acetate was determined by solution method
To understand the relationship between dipole moment and molecular electrical properties
The experimental technique of determination of dipole moment by solution method
I. basic principles
I. dipole moment and polarization degree
The molecular structure can be approximated by the stone as the electron. And the structure of the skeleton (nucleus and inner electrons). Because of the difference in the configuration of the molecular space, the center of negative charge may be overlapping or not, the former is called a non-polar molecule, which is called a polar molecule.
Figure 1 electric dipole moment schematic
In 1912, Debye proposed the concept of "dipole moment" mu to
measure the size of molecular polarity, as shown in figure 1, which is defined as
EMBED Equation. 3 (1)
Q is the charge in the center of positive and negative charge, d is the distance between positive and negative charge center, mu is a vector, and the direction of its direction is from positive to negative. The order of magnitude of the a
