Time resolved spectroscopic measurement of a polymer undergoing small amplified perturbation- relaxation cycle can provide information regarding the relaxation characteristics of the polymer. It can in fact distinguishes between segments within the same polymer. In order to eventually be able to study complicated biopolymers we have chosen manmade polymers as model systems and constructed a specialized instrument. We describe the instrument, its operation, and resulting data.
