Hi, I have run 19F and 31P dosy using ledbpgg2s program from Bruker, I obtain good decreasing curves as expected, with usual parameter range, but the diffusion coefficient values calculated from T1/T2 module from Bruker, as well as Dynamic Center are 1000 times bigger than expected, while values calculated from NMR notebook seem correct. I have checked H2O D value before my experiment which is 1900µm2/s as expected at 25°C. has anyone an idea? Many thanks! Anne
