摘要:
Circuit modifications are described which enable a Varian A‐60 spectrometer to be used for relaxation studies of chemically‐shifted protons.T1andT2values greater than 0.1 sec can be measured on the modified instrument at ambient temperature. Owing to severe convection effects in the probe assembly, relaxation measurements are made with difficulty at other temperatures. Methods of time‐averaging relaxation data are also discussed.
