TLDR
In this paper, the authors used the signal from the first electronically excited state of a premixed laminar flame to ground (at 305.4nm) to determine the viability of using OH chemiluminescence as an active control parameter for high-pressure, premixed flames.About:

Local measurements of the time-dependent heat release rate and equivalence ratio using chemiluminescent emission from a flame
Yannis Hardalupas,M. Orain +1 more
TL;DR: In this article, the effects of strain rate and equivalence ratio on intensity of chemiluminescence and the ability of intensity to indicate heat release rate were evaluated in flat flames.

Numerical evaluation of equivalence ratio measurement using OH∗ and CH∗ chemiluminescence in premixed and non-premixed methane–air flames
TL;DR: In this article, the effects of flow strain rate and equivalence ratio on the chemiluminescent intensities of electronically excited OH (A{sup 2 sigma}, denoted as OH{sup *}) and CH (A {sup 2 ndelta}, referred as CH{sup*}) species in laminar premixed and non-premixed counterflow methane-air flames, at atmospheric pressure, are studied.

An experimental study on the effect of pressure and strain rate on CH chemiluminescence of premixed fuel-lean methane/air flames
TL;DR: In this paper, the authors investigated the possibility of using chemiluminescence as an active feedback control parameter to deduce the equivalence ratio, and therefore NO x production and combustion stability, for premixed flames at high pressure.
