Definition of space group in English:

space group


  • Any of 230 symmetry groups used to classify crystal structures.

    • ‘The crystals also differ in their space group and in the unit cell dimension.’
    • ‘These crystals have high mosaicity, diffract to low resolution, and were tentatively assigned to the P23 space group.’
    • ‘X-ray crystallographic studies revealed that the KP - 23 molecule crystallizes in epimeric form in the triclinic P1 space group and possesses four chiral centers.’
    • ‘From the crystallographic data, the space group has been found to be orthorhombic and the unit cell dimensions have been determined.’
    • ‘The orthorhombic space group of the crystals implies that each unit cell contains four trimers.’
