Short summary
We developed the relationship between the chemical and optical characteristics of BrC in Guangzhou, China. We determined wavelength-dependent mass absorption coefficients of organic aerosol with different sources. The BrC absorption coefficient was associated with N-containing ion fragments and depended on their degrees of unsaturation/cyclization and oxygenation.
