Lattice Vibrational Impurity Modes in LiH:D and LiD:H Crystals
Some time ago, Misho(1) carried out an experimental study on the effects of isotopic composition on the fundamental infrared absorption frequency (ωt,0) of Li(H,D) mixtures. His principal finding was that very small (~5%) concentrations of D- were sufficient to shift this frequency from that characteristic of LiH to a value close to that of LiD.
