Room-temperature absorption spectroscopy of the over(A, ∼)1 A2 ← over(X, ∼)1 A1 transition of formaldehyde has been performed in the 30140-30790 cm-1 range allowing the identification of individual lines of the 201 403 and 202 401 rovibrational bands. Using tunable ultraviolet continuous-wave laser light, individual rotational lines are well resolved in the Doppler-broadened spectrum. Making use of genetic algorithms, the main features of the spectrum are reproduced. Spectral data is made available as Supporting Information.
