The Electrostatic Contribution to Hindered Rotation in Certain Ions and Dipolar Ions in Solution. III

In the present paper we shall extend the previous methods to a relatively complicated molecule, glutamic acid: $$\begin{array}{c}\hspace{0.17em}\mathrm{COOH}\text{\hspace{0.17em}(1)}\\ \mathrm{\hspace{0.17em}\; |}\\ \hspace{0.17em}{\mathrm{CHNH}}_3^{+}\text{\hspace{0.17em}(3)}\\ \mathrm{\hspace{0.17em}\; |}\\ ({\mathrm{CH}}_2{)}_2\\ \mathrm{\hspace{0.17em}\; |}\\ \hspace{0.17em}\mathrm{COOH}\text{\hspace{0.17em}(2).}\end{array}$$ Other calculations will also be made and an empirical relationship among the effective dielectric constants found in this and earlier papers will be pointed out.
