Abstract

It is often difficult to distinguish between morphology-dependent resonance and Raman intensity features in nonlinear Raman spectra of organic fuel droplets. In theory the morphology-dependent resonances can be deconvoluted from single-shot spectra, but in practice this is difficult because of shot-to-shot parameter variation. Frequency-analysis methods have been applied to spectra obtained from fuel sprays, and correlation analysis is found to be quick and easily interpreted.
