i am trying to get quantitative spectra of cholesterol disolve in cdcl3
90° pulse , inv gated (decoupling only during FID) 400s recycling delay (>
5 * t1 )
machine is avance 500
this is what i get :

sum of all integral (norm) is 100
peaks at 140 end 121 ppm shoud have the same integral , right ?
so , what can be wrong ?
thanks to all
