Abstract
The absorption spectrum of gaseous fulminic acid, HCNO, was recorded in the above range with a resolution of $1.5 cm^{-1}$ to determine the frequency of the low frequency bending mode, $v_{5}$. However, instead of one strong perpendicular band with weak “hot” bands, as had been observed for the $v_{4}$ $absorption^{1}$ at $538 cm^{-1}$, an irregular series of strong, sharp absorptions is observed. The reasons for attributing these absorptions to vibrational transitions in HCNO rather than to other substances will be presented. A tentative assignment of the observed spectrum will be discussed, based on results of the analysis of millimeter wave data and on the observed absorptions in the range $500 cm^{-1}$ to $700 cm^{-1}$, which we have remeasured.
