The invention relates to methods of assessing the polymorphic form of a substance by assessing Raman-shifted radiation scattered by a particle of the substance. The method is useful, for example, for assessing particle sizes and size distributions in mixtures containing both particles of the substance...http://www.google.de/patents/US20060124443?utm_source=gb-gplus-sharePatent US20060124443 - Control and monitoring of non-resonant radiation-induced nucleation, crystallization, and polymorph formation
