Code and derived data for: Reading the Delayed-Fluorescence Rate Law from Flash-Lamp Decays with Weak-Form Regression

The package wfkin, benchmark sets B1-B4 with seeds, the analysed decay series, derived tables and figure scripts. Raw decay exports are in the time-resolved PL record. Methods: Scripts are written in Python 3 (NumPy, SciPy, pandas, matplotlib; RDKit for structure drawings where used). Each script reads the tables of this record or the raw files of the experiment records and writes numerical tables and figure panels (vector PDF with a 600-dpi PNG). Package wfkin: forward model of multichannel-scaling delayed-emission acquisitions, weak-form regression with compactly supported test functions, strong-form references (Poisson maximum likelihood, tail fit) and a temperature-law grammar; seeded benchmark sets B1-B4; analysis of the measured decay series (scripts s01-s18). Companion paper: Reading the Delayed-Fluorescence Rate Law from Flash-Lamp Decays with Weak-Form Regression (manuscript prepared for Analytical Chemistry). Raw instrument files are in the experiment records of the series (AFM, UV-Vis, DRS, ellipsometry, PL, time-resolved PL, CV, DSC/TGA, XRD, FTIR, NMR/MS, electron microscopy, J-V, impedance, DFT).
