Dear Norberto, Thanks for your rapid answer. > The obvious way out from this second problem can be a different > preparation of the sample, changing "texture coefficients", just > aiming to detect the 'missing informative peaks'. > The sample was in-situ crystallised by putting a drop of the mother liquid on a silicon substrate and letting evaporate the solvent. This should favour a random orientation of the crystallites, not?
