Abstract
The unresolved Q-branch profiles in the Raman spectra of'
nitrogen in premixed, laminar, methane-air, propane-air and butane-
air flames with lean to stoichiometric fuel-air equivalence
ratios have been recorded experimentally and used to determine
flame temperature s with a precision of about 1% using an iterative
computer program which fitted calculated nitrogen spectra to the experimentally recorded spectra. Axial and radial temperature profiles in these flames are presented and the results compared with calculated adiabatic flame temperatures.
