Paper Abstract

The application of two-color incoherent cross-correlation spectroscopy to study ultrafast processes in organic liquids and solutions is discussed. This kind of time-resolved spectroscopy is based on using two broadband correlated pulses of long duration with different central frequencies. Its time resolution is determined by the cross-correlation time of the intensities of used radiations. The statistical properties of the radiations have been investigated. The developed technique allowed us to perform kinetic measurements with femtosecond resolution on the ordinary nanosecond laser spectrometer modifying it in a comparatively simple way. The present technique was demonstrated and tested by studying subpicosecond Kerr dynamics in a number of organic liquids and their mixtures. An approach is also proposed to study the population relaxation of electronic and vibronic states of organic molecules including non-luminescent ones.
