Librational tunneling levels of NH, + ions in an (NH,),SnBr, single crystal were determined by studying the proton Zeeman relaxation. The relaxation rate speeds up when any of the tunnel frequencies vI equals n va (n = f , 1, 2). where v0 is the proton resonance frequency. The energy separation betw
