Detection of the 3.4 Micron Emission Feature in Comets P/Brorsen-Metcalf and Okazaki-Levy-Rudenko (1989r) and an Observational SummaryWe are continuing a survey of the 3 μm spectral region of comets, including the broad 3.4 μm emission feature due to C—H bonds in organic molecules. One goal is to determine how the strength of the emission band varies with heliocentric distance r in comets. This depends on both the production rate of the organic molecules and the emission mechanism, neither of which is well determined at present.
