When a compound exhibits polymorphism—the ex-istence of more than one crystal structure—it
may be important to obtain a particular polymorph under controlled and reproducible …

The simultaneous appearance of polymorphs of a substance has long been recognized but
rarely noted or systematically studied. This phenomenon can be useful in the investigation of …

The century following the determination of the first crystal structure by the Braggs 1 has yielded
encyclopedic precise information on molecular geometry. The interatomic distances for …

Whereas much of organic chemistry has classically dealt with the preparation and study of
the properties of individual molecules, an increasingly significant portion of the activity in …
