Infrared spectra of formaldehyde have been taken at Florida State University with a resolution of $0.02cm-1$. A region from 2660 $cm-1$ to 3040 $cm-1$ was scanned at room temperature using 0.25 meter to 2 meter paths and pressures of 200 to 600 microns. Assignments have been made to the overlapping $v1$ and $V5$ bands of formaldehyde, and molecular constants have been determined. Analysis of the absorption strengths of assigned transitions is in progress.
