摘要：

Temperature-dependent infrared spectra of two samples of layered zirconium phosphates intercalated with n-CH3(CH2)10CH2NH2 and n-CH3(CH2)12CH2NH2 have been recorded and studied. The purpose of the work is to understand the mechanism of phase transitions at the molecular level. Collective phonons and localized defect modes have been identified, and their thermal behavior has been studied. The transition is not first order and proceeds through several steps. Upon heating, chains contain GTG′ kinks but no liquidlike structures are observed. © 1990, American Chemical Society. All rights reserved.
