摘要
The temperature dependence of the IR-spectra of (NH4)(2)SO4 and (ND4)(2)SO4 has been studied and correlated with the phase transitions and nuclear magnetic resonance data. The anomalous DMR behaviour of (ND4)(2)SO4 is also reflected in its infrared spectrum. The infrared spectrum of (NH4)(2)SO4 argues in favour of increased hydrogen bonding below the ferroelectric transition point.
