HIGH RESOLUTION COHERENT THREE-DIMENSIONAL SPECTROSCOPY OF IODINE

Abstract

The heavy congestion found in many one-dimensional spectra can make it difficult to study many transitions. åÊA new coherent three-dimensional spectroscopic technique has been developed to eliminate the kind of congestion commonly seen in high resolution electronic spectra. åÊThe molecule used for this test was Iodine. åÊA well-characterized transition (X to B) was used to determine which four wave mixing process or processes were responsible for the peaks in the resulting multidimensional spectrum. åÊThe resolution of several peaks that overlap in a coherent 2D spectrum can be accomplished by using a higher dimensional (3D) spectroscopic method. This talk will discuss strategies for finding spectroscopic constants using this high resolution coherent 3D spectroscopic method.
