Key Points

This research aims to improve the analysis of optical spectrometric data by developing a model that better accounts for photon transport and scattering effects.
Developed a physics-guided computational framework that integrates electrodynamic theory and Monte Carlo simulations.
Conducted simulations using spherical polystyrene suspensions over varying sizes and concentrations.
Utilized cross-validated regression to infer effective parameters for quantitative comparisons with measurements.
The model accurately reproduces UV-Vis extinction spectra with pronounced nonlinear concentration dependence.
It shows that predicted optical densities (5-9) are higher than actual measured signals (<4) within the instrument's dynamic range.
The framework allows for consistent extraction of refractive indices across different particle sizes and data sets.
