Polarizability of stereoregular polymers

Area of Science:

• Theoretical chemistry
• Polymer physics
• Condensed matter physics

Background:

• The Genkin-Mednis approach is a theoretical framework for calculating the longitudinal polarizability of infinite polymer chains.
• Accurate calculation of polarizability is crucial for understanding polymer behavior in electric fields.

Purpose of the Study:

• To revisit and refine the Genkin-Mednis approach for calculating longitudinal polarizability.
• To address a specific error in the dipole oscillator strength formula within the existing framework.

Main Methods:

• Re-examination of the Genkin-Mednis formalism.
• Correction of a small error in the dipole oscillator strength formula.
• Analysis of the resulting mathematical form of the polarizability.

Main Results:

• The correction leads to a manifestly antihermitian form for the dipole oscillator strength.
• This revised form enhances consistency in the computation of related physical quantities.
• The updated approach provides a more robust theoretical tool for polymer polarizability.

Conclusions:

• The corrected Genkin-Mednis approach offers improved accuracy and consistency.
• This work contributes to a better theoretical understanding of polymer chain response to electric fields.
• The findings facilitate more reliable predictions in polymer science and materials research.
