Abstract: The formaldehyde spectrum was recorded at $0.022 cm^{-1}$ resolution with the Florida State University grating spectrometer. Approximately 5000 transitions were measured in the region from 2630 to $3030 cm^{-1}$. Lines have been assigned to the fundamental bands, $\nu_{1}$ and $\nu_{5}$ for J $\leq$ 25 and K $\leq$ 9. In addition, partial assignments have been made to the three combination bands, $\nu_{3} + \nu_{6} , \nu_{2} + \nu_{4}$ and $\nu_{2} + \nu_{6}$. To obtain molecular parameters, energy levels have been calculated through the diagonalization of the rigid asymmetric rotor with the Kivelson-Wilson terms evaluated for distortion effects. A non-linear least squares fit of combination differences between levels with J $\leq$ 24 and K $\leq$ 9 has determined ground state constants. In addition, upper state energy levels of the more thoroughly assigned bands have been fit to obtain upper state inertial parameters.
