摘要: The infrared spectra of the ND‐stretching bands dilute NH3D+ in NH4ClO4 are presented. studied over temperature range from 3 K to room temperature. At low temperatures, is preferentially oriented. extent orientation at a given depends on deuterium concentration and thus ions. As raised, various collapse due variety dephasing processes. temperature, process phonon‐assisted tunneling. accomplished by interaction among librational states. still higher bandwidth stochastic motion ammonium
