Crystals of l. asparagine and their structure
Abstract
For the correct orientation, 100 crystals were re-examined. The results of the re-examination and calculations of the probability of correct orientation are given in the tables (see the article). Using asparagine as an example, the regularity of the decrease in the number of developed forms as the crystal sphere grows is demonstrated with exceptional clarity and distinctness. Furthermore, during subsequent crystallization, the appearance of any new forms not observed in the preceding crystallization was never observed. From all the experiments described above, it clearly follows that there exists possibility of obtaining a much greater number of forms during the crystallization of a sphere, compared with what we observe during the free growth of crystals of the same compound.
