Abstract

We investigated how partial fluorination of a phenyl group affects the CH stretching vibrational absorptions of polystyrene-based optical fiber materials. We confirmed that the fluorination can decrease not only number density of CH bonds but also the CH absorption per bond. Moreover, by quantitatively correlating the CH stretching vibration absorption spectra with anharmonic vibrational potential, we suggested that the decrease efficiency of attenuation depends on the substituted position in the benzene ring and the chemical structure itself.
