indirect photolysis

https://doi.org/10.1351/goldbook.14758
Degradation of a contaminant through interaction with other molecules in solution that have absorbed light energy. This can occur through energy transfer or by chemical reaction with short-lived reactive species.
Note: Dissolved humic and fulvic acids are good examples of photoactive compounds that can increase the degradation of contaminants through indirect photolysis.
