Abstract
A full set of the energy characteristics describing dissociation (Do(Sr–OH) = 401.8 ± 3.0 kJ/mol), ionization (Io(SrOH) = 5.372 ± 0.042 eV), and radiation power in the visible spectrum where the brightest bands with momenta Re (au) of transitions A2Π → X2Σ (2.08 ± 0.15) and B2Σ → X2Σ (1.79 ± 0.13) are located is determined for strontium monohydroxide via spectrophotometry, and from a physical model.

Notes
The error in C corresponds to the uncertainty in q.
Value a = 1.1 was given for T = 2500 K in [21]. It was recalculated to the temperature of the flames of ∼2700 K used here, at which self-absorption was highest but still no more than 20%.
