摘要: Abstract Total synchronous fluorescence spectroscopy (TSFS)-based three-way array sample × excitation wavelength × Δλ has inherently complex data structure. Multivariate curve resolution alternating least square (MCR-ALS) analysis is a soft mathematical modelling technique that can be used to retrieve pure spectral and contribution profile of the fluorophores multifluorophoric mixture provided it applied bilinear sets. In present work, possibilities generating two-way arrays by (i) unfolding (ii) augmenting TSFS-based were studied. Bilinear characteristics obtained tested subjecting them MCR-ALS analysis. It was found lack analytical–mathematical relationship between along excitation wavelength mode offset do not allow application on augmented TSFS set. Moreover, augmentation procedure chemical-mathematical rank subsequently sets ‘not independent’ each other. Two-way sample × (excitation wavelength × Δλ) sample have symmetrical structure, i.e., both equal chemical making highly attuned
