EFFECTS OF UNIAXIAL STRESS UPON THE VISIBLE RUBY ABSORPTION SPECTRUM.
Abstract
An investigation of the effects of uniaxial stress upon the ruby absorption spectrum was conducted using a photographic technique. To reduce the effects of thermal broadening of spectral lines, ruby samples were immersed in liquid nitrogen. A heretofore uninvestigated series of satellite absorption lines was found near the red doublet. Intensity is dependent upon the concentration of chromium in the lattice. This suggests that the newly observed lines are caused by exchange interactions between chromium ions. The effects on these lines of uniaxial stress was measured as a function of polarization and orientation of the c-axis. A linear dependence of spectral line position on stress, a general shift of all lines toward the red, and a marked splitting of the satellites were observed. A theoretical analysis from the point of view of crystalline field theory was conducted in the weak field scheme.
