The far-infrared spectrum of formamide (HCONH2) has been recorded at high resolution and over 9000 vibration-rotation lines assigned. Molecular parameters from the rovibrational analyses of the unperturbed 1201 out-of-plane vibration band have been obtained for the ground state and the excited state. An analysis of the complicated resonance system between the 901, 1101, and 1202 bands has also been carried out. The mid-infrared spectrum of formamide has been recorded at low resolution and assignments for the fundamental, combination, and overtone bands in this region are given. The Large Amplitude Motion (LAM) of the out-of-plane mode has been reanalyzed using the new parameter set.
