Abstract

We have combined the techniques of frequency-modulation spectroscopy (FMS) and photochemical-modulation spectroscopy to carry out high-resolution, high-sensitivity absorption measurements on the formyl and amino radicals. Using the (0,9⁰, 0)-(0,0¹, 0) band of the Ã,²A″- {Mathematical expression},²A′ transition of HCO at 614 nm, we obtained a sensitivity limit for absorption of 1.5×10^-6. Reconstructed spectra of several HCO lines are presented.
