Laser-induced fluorescence and excitation spectra of formaldehyde in the A–X 410 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 in situ diagnostic measurements.
