✦ Synopsis

The configurational energies, the characteristic ratio and the temperature coefficient for a polysilane chain with the third-order interaction are calculated. The characteristic ratios ((R2)/n12)o~ and (($2)o/nl2)~ are 3.57 and 0.575, respectively, and the temperature coefficient is -3.0 x 10 -3 deg -t. These results are less than those in the second-order interaction approximation. The third-order interaction approximation are useful for calculating the dimensions of polymer chains.
