Hi,
Can anyone show me how to program (XwinNMR 3.5pl6) the hyperbolic
semiconstant time evolution periods of Lin & Wagner (1999, J. Biomol.
NMR, 15:227)?
So far what I've tried won't pass through ased and gives and error with
pulsdisp. I've had problems in the past with coding too much run-time
math. I've also put the initial if loop into a compile-time, rather
than run-time loop but it didn't help.
Thanks,
David
(basic framework; hangs ased):
if "td1 > 2*(3.6m/in0+1)" goto lab11 ; t1max > 4del
3u ; t1max < 4del
"AT=(td1 / 2 - 1) * in0"
goto lab12
lab11, 3u ; t1max > 4del
if "d0 >= 3.6m" goto lab2 ; & t1 > 4del
lab1, 3u ; & t1 < 4del
"xi=1/(1/d0+1/(2*del))" ; d0 < 2*del
"d20=d0-xi"
"d28=del-xi"
goto lab20
lab2, 3u ; t1max > 4del & t1 >
4del
"xi=del"
"d20=3u+d0-xi"
"d28=3u"
goto lab20
lab12, 3u ; t1max < 4del
"xi=1/(1/d0+1/del-2/AT)"
"d20=d0-xi"
"d28=del-xi"
goto lab20
lab20, 3u
