Measurements of quadrupole-interaction-resolved NMR on oriented185Pt,189Pt, and

Abstract

We report on measurements of quadrupole-interaction-resolved nuclear magnetic resonance on oriented nuclei ͑QI-NMR-ON͒ of 9/2 ϩ 185 Pt (T 1/2 ϭ1.2 h͒, 3/2 Ϫ 189 Pt (T 1/2 ϭ10.9 h͒, and 3/2 Ϫ 191 Pt (T 1/2 ϭ2.9 d͒ in hcp-Co. Ratios of quadrupole moments were determined to be Q( 185 Pt)/Q( 191 Pt)ϭϪ4.46(13) and Q( 189 Pt)/Q( 191 Pt)ϭϩ1.235(8). ͓S0556-2813͑98͒01805-6͔
