Laser-induced fluorescence and excitation spectra of formaldehyde in the <i>A–X</i> 4<sub>1</sub><sup>0</sup> band at 370 nm are recorded in the primary flame front of a Bunsen flame. An examination of partition functions shows that this excitation can minimize temperature bias for formaldehyde <i>in situ</i> diagnostic measurements.
