Article Synopsis
- The study investigates how mononitropyrene isomers interact under simulated atmospheric conditions, focusing on their ground state absorption and reactive intermediates.
- Different orientations of the nitro group affect the photochemical properties of the isomers, with the 2-NO(2)Py isomer demonstrating the largest red shift and lowest oscillator strength.
- The research reveals that most isomers have very low fluorescence yields and only certain isomers exhibit phosphorescence, indicating that many decay processes occur through non-radiative pathways, particularly influenced by hydrogen bonding with the nitro group.
1-Nitropyrene (1NPy) is the most abundant nitropolycyclic aromatic contaminant encountered in diesel exhausts. Understanding its photochemistry is important because of its carcinogenic and mutagenic properties, and potential phototransformations into biologically active products. We have studied the photophysics and photochemistry of 1NPy in solvents that could mimic the microenvironments in which it can be found in the atmospheric aerosol, using nanosecond laser flash photolysis, and conventional absorption and fluorescence techniques.
