Spectral-diffusion broadening in a protein follows a power law in time quite
in contrast to the respective behavior of a glass which is governed by 
-laws.
This specific power law behavior is independent of the aging time of the
protein at low temperatures. Possible orgins of the power law are discussed:
a modified TLS-model and diffusion-like motions in frequency space.
