Abstract
Correlation spectroscopy principle was applied to study Raman signal of the SERS active system consisting of Ag colloid and copper(II) 5,10,15,20-tetrakis (1-methyl-4-pyridyl) porphyrin. A multichannel Raman spectrometer was used to record sets of consecutive Raman spectra with sampling times of tenths or units of seconds. SERRS spectra of two SERS-active formations assigned to the porphyrin molecules on the surface of Ag particles and in the aggregates were isolated by means of the statistical noise analysis. It has been proved, that Raman correlation spectroscopy can be employed to resolve complete Raman spectra coming from either small or large objects levitating in liquid.
