%X A standardized procedure for the accurate measurement (1% error) (in reasonable time (10-20 min)) of critical pulse lengths is recommended. It uses the 2d-n.m.r. scheme: [t1t2] &#8594; [f1t2] [t2] &#8594; [f2 &#8801; &#952;] where t2 is an incremental time, f1 is made to vanish by selection of a single point region and f2 is equivalent to pulse length (angle &#952;). Pulse imperfections are readily detected. To make the method totally general sources of these imperfections should be corrected. Applications to T1 and 2d-J n.m.r, measurements are outlined.
