1 13C-13C PROTON-DRIVEN SPIN- DIFFUSION (PDSD) A 200 MM (NH4)2SO4 SOLUTION WAS ADDED TO A 1.15 MM SH3 SOLUTION (PH=3.5) AT A VOLUME RATIO 1:1. THE SOLID SAMPLE WAS OBTAINED BY PRECIPITATION, CHANGING THE PH TO 7.5 IN NH3 ATMOSPHERE. SOLID SAMPLE ? 7.5 AMBIENT 280
2 15N-15N PROTON-DRIVEN SPIN-DIFFUSION (PDSD) A 200 MM (NH4)2SO4 SOLUTION WAS ADDED TO A 1.15 MM SH3 SOLUTION (PH=3.5) AT A VOLUME RATIO 1:1. THE SOLID SAMPLE WAS OBTAINED BY PRECIPITATION, CHANGING THE PH TO 7.5 IN NH3 ATMOSPHERE. SOLID SAMPLE ? 7.5 AMBIENT 280
