WebUnit cells “Crystals are built up of regular arrangements of atoms in three dimensions; these arrangements can be represented by a repeat unit or motif called the unit cell.” 2 In crystallography, all the crystal unit cells can be classied into 230 space groups. Some basic knowledge about crystallography is necessary for a well understanding of powder XRD … WebDec 16, 2024 · The refractive index ( n) is the ratio of the velocity ( v) of light in a vacuum to the velocity in the crystal: blankn = vvacuum / vcrystal. Because light passes through a vacuum faster than through any other medium, n always has a value greater than 1. High values of n correspond to materials that transmit light slowly.
