2H-NMR Study of ammonium ion rotational tunneling and reorientation in (ND4)2SnCl6 single crystal

III. Low magnetic field measurements

Abstract

Because of the quadrupole interaction, the2H-NMR spectra of a tunneling ND +4 ion depend on the Larmor frequencyv 0 and the tunneling frequencyv t , when both frequencies are less than 20 MHz. Calculated single crystal spectra visualize features to be expected. Significant broadening and asymmetry are observed at level crossing regions aroundv t =v 0 orv t =2v 0. Angular, frequency and temperature dependences of the spectra are studied using an (ND4)2SnCl6 single crystal. Experimental spectra obtained for different frequencies at 4.2K are fitted withv t as a parameter. The tunneling frequency is also checked by measurements of the deuteron spin-lattice relaxation timeT 1 as a fuction ofv 0. Both methods give consistentlyv t =7.15±0.10 MHz.
