Abstract
We consider the theory of time-dependent fluctuations in single molecule sp
ectroscopy. In particular, the relation between stationary spectral diffusi
on processes and photon counting statistics is investigated. Within linear
response theory, a general relation between Mandel's Q parameter and a thre
e time dipole correlation function is obtained. For a prototype spectral di
ffusion process, an exact solution of Q is found which exhibits rich types
of physical behaviors.
