COMMENTS: Absolute absorption cross sections at room temperature (294 ± 2 K) for the
A 1A2−X 1A1 electronic transition of formaldehyde have been measured over the spectral range 30285−32890 cm-1 (304−330 nm) using UV laser absorption spectroscopy

Absorption cross sections were obtained at an instrumental resolution better than 0.09 cm-1 (∼0.0009 nm), which is slightly broader than the Doppler width of a rotational line of formaldehyde at 300 K (∼0.07 cm-1), and so all but the most closely spaced lines could be resolved
