Abstract
Fine structures of the vibrational spectrum of OH- in NaCl have been investigated by their dependence on the OH- concentration, temperature and uniaxial stress. The absorption bands of A and C at 3651. 2 and 3655.2 cm-1 are ascribed to the tunneling motion of the off-center impurity of OH-. The stress splitting factor of the tunneling levels has been estimated to be B(S11-S12)=0.96±0.10 cm-1/108 dyn cm-2 in the ground state and it is about 1.4 times larger in the vibrational excited state.
