Replication Data for: Aqueous-phase Direct Photolysis of Phenolic Compounds - the Formation of Dimers and Their Contributions to Atmospheric Brown Carbon

This dataset contains the experimental, analytical, and visualization-ready data associated with the study “Aqueous-phase Direct Photolysis of Phenolic Compounds - the Formation of Dimers and Their Contributions to Atmospheric Brown Carbon”. The dataset includes the complete numerical data used to generate all figures in both the main manuscript and the Supplementary Information.

Methods Overview:
Photolysis experiments were conducted in aqueous solution under controlled UVA/UVB irradiation. Mass spectrometric analyses were performed using Thermo Orbitrap and Waters QTOF instruments, and LC–MS data were processed using Thermo FreeStyle. UV–Vis absorption measurements were obtained using a diode-array spectrophotometer. Full experimental and analytical details are provided in the associated manuscript.

Purpose:
This dataset is provided to support transparency, reproducibility, and reuse of the results presented in the manuscript. The files enable independent regeneration of all figures, quantitative analyses, and data visualizations associated with the study.
