Fluctuation Spectroscopy by Tunable Energy Compensation: Application to Radiator Reorientation Kernels

Abstract
A new method for investigating fluctuations in macroscopic coherences is suggested and demonstrated by measurement of radiator reorientation kernels in Stark-tunable infrared transitions of C13 H3F. The dominant (ΔM=1) kernel is obtained by a scale transformation from the shape of a curve of two-pulse photon-echo intensity versus Stark voltage, at fixed large echo time delay.
