Abstract
Quasielastic light scattering (QLS) is a powerful technique for studying the fluctuations of molecular and particulate systems. Its use in complex systems such as intact living cells is limited by the predominance of scattering from large structures other than the components being studied. We propose and analyze a novel method analogous to QLS but selective for molecules or particles bearing a particular labeling chromophore, using correlation spectroscopy of a quasicoherent component of double-resonance fluorescence (QDORF).
