I want to get second moment from fid data. Does anyone know how to do it or is there any free computer program solving such problem? thanks a lot! asked Jan 03 '13 at 03:38 |
Generally if you fit the rigid signal (corresponding to the rapid decay) with an Abragam function, i.e. exp(-0.5(at)^2)sin(bt)/(bt), then the second moment is calculated as M2=a^2+1/3*b^2 answered Jan 07 '13 at 16:08 Roja Thank you very much for your answering! - Minghui Zhang (Jan 08 '13 at 06:49) |
