Calibration of Raman spectroscopy signals for measurements of methane-air tubular flames.

- Abstract
This paper addresses a challenging approach to calibrating visible Raman spectroscopy data when investigating laminar methane-air tubular flames, which struggles against low signal levels, signal interferences, etc. The literature study considers only the crosstalks between the CO2 and O2 vibrational Raman lines. This study will expand the coverage of the crosstalks from H2 rotational Raman lines onto CO2, O2, N2, and H2O by employing four more off-diagonal elements in a calibration matrix. The matrix elements are determined using proper calibration flames and calculated compositions in their post-flame zone. The polynomials represent the calibrated temperature dependence of the non-zero matrix elements. Temperature-dependent response curves of each calibration element of this study and the literature study are then compared. It also found that most of the matrix elements in this study, when normalized by their values at room temperature, behaved very closely to those previously reported by another researcher group.
