摘要

We have studied infrared spectral hole burning of the N-D stretching bands of NHaD+ in salt [(NH4)2Co0.25Ni0.75(H2O)6(SO4)2] at 10K. We have observed that the spectral line broadening occurred on a logarithmic timescale,which is consistent with the theoretical prediction of a standard two-level system. The temperature of 10 K is also beyond the temperature limit in previous studies on spectral diffusion.
