| 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 | ||
