LIFSIM; a free online simulation tool for NO and O2 LIF and absorption spectra

LIFSim allows the simulation of absorption and LIF spectra (excitation and emission) for NO and O2. Correction factors for imaging diagnostics can be evaluated. Spectroscopic data of NO A-X and O2 B-X is implemented. The simulations include pressure line broadening and shifiting, and quenching. LIF signals are calculated using a three-level non-transient linear model.

In the full software version, experimental spectra can be used as input and parameters, e.g. temperature, can be fit to the measured data.
