Abstract:

The Earths atmosphere is opaque to most of the infrared band between 1 and 100 microns. One of the partial windows between 3 and 4 microns gave Sinton an opportunity to detect three small dips in the reflection spectra associated with the visual dark regions of Mars. The dips are not associated with the light arid areas of the planet. One small dip on the shoulder of the descending spectrum is at 3.43 microns. All C-H bond molecules heavier than methane have a strong infrared resonance absorption at 3.46 microns. It is quiet probable that organic matter is on Mars, but its origin is still an open question. More infrared reflection spectra of biological materials are needed, particularly in spectral regions where molecules of biological origin have very definite characteristics
