Popis:	Two polymorphic forms of olanzapine were investigated as a function of temperature in a range from 100 to 420 K and as a function of hydrostatic pressure from 0 to 1300 MPa using positron annihilation lifetime spectroscopy. In the crystallographic structure of both investigated forms exists component ascribed to positronium formation. The lifetime value of o-Ps changes nonmonotinicaly from 1.0 to 1.6 ns as a function of temperature. (© 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
