Abstract

The absorption spectrum of gaseous fulminic acid, HCNO, was recorded in the above range with a resolution of $1.5 c m −1$ 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 $v 4$ $a b s o r p t i o n 1$ at $538 c m −1$ , 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 $500 c m −1$ to $700 c m −1$ , which we have remeasured.
