Combining Experimental Laser Spectroscopies and Molecular Modeling: Can an New Approach Shed More Light on Primary Processes Involved in Photopolymerization Reaction ?

In this paper, new techniques for the investigation of primary processes involved in photopolymerisation reactions are presented. Experimental techniques such as nanosecond time-resolved FTIR or laser induced photoacoustic calorimetry are discussed with respect to their potential applications for the investigation of photopolymerization processes. On the other hand, molecular modeling results obtained at high level of theory are shown to provide unique thermodynamical data on the processes that govern the overall efficiency of the photoinitiating systems. A new approach that combines both experimental techniques and molecular modeling is developed and presented on the basis of recent selected examples.
