L (+) グルタミン酸ナトリウムのX線的研究

Abstract

Crystallographic studies by X-rays were made of sodium L(+)-glutamate. These crystals belong to the rhombic system and the size of their unit cell is: a0=15.27Å, b0=18.02Å, c0=5.61Å, ρ=1.589. The space group of sodium L(+)-glutamate is D24-P-212121, and the equivalent point of these space groups is four. Since the number of molecules in one unit cell is eight, two kinds of crystallographically different sodium L(+)-glutamate are present in one unit cell.
