Abstract:

The temperature dependence of the rotating frame relaxation time T1 rho for protons in powdered lithium hydrazinium sulfate, LiN2H5SO4, has been determined from 140 to 495K. These measurements indicate that the -NH2 part of the N2H5 ion executes 180 deg flips about the bisectrix of the H-N-H angle. Evidence for motion of the entire N2H5 ion was also obtained. Separate reorientation and diffusion motions of the N2H5 ion could not be distinguished, although evidence that the N2H5 motion detected in the T1 rho measurements includes diffusion is obtained by comparing the T1 rho results with the temperature dependence of the proton second moment.
