Abstract : Under excitation with a carbon arc a fluorescence of formaldehyde, which exhibits a very simple spectrum, was found in the gaseous state. The shortest fluorescence waveband coincides with the longest absorption waveband, which very probably generates the greatest part of the fluorescence bands. This can be understood, then, by two vibration frequencies of the ground state, 1713 and 1023/cm, which were also found in the Raman spectrum. Even higher vibration levels of the first one occur. A formula for the bands is given. The coupling member of both vibrations is rather large. (Author)
