Abstract

The ground state rotational spectrum of protonated formaldehyde, $H_{2}COH^{+}$, has been identified and assigned following the infrared detection by Amano and $Warner^{1}$, using a magnetically confined extended negative glow discharge as a production source. The molecular constants have been determined more accurately. These parameters provide the pure rotational transition frequencies which are accurate enough for radio astronomical searches for this ion in interstellar molecular clouds.
