In H2O, the 31P NMR spectrum of the compound gives 2 lines shifted from each other by about 1ppm, corresponding to the hydrate and ketone in the ratio of 60:40. You want to measure the rates of interconversion between them in the range of 0.1-3.0 per second using a cross relaxation method. Both the hydrate and ketone have T1's of 5.0 second and linewidths, delta v1/2 of 2 hz. The experiments are performed in a field such that the 31P...
