The abundance of CH3D and the D/H ratio in Jupiter.
From observations of the nu 2 parallel band of mono-deuterated methane (CH3D) in the Jovian atmosphere, we have deduced a CH3D abundance and mixing ratio and a value for the D/H ratio in this planet, with due regard to the problems of Jovian atmospheric structure and deuterium fractionation. We find the D/H ratio to be significantly less than the terrestrial value and discuss some of the implications to the early history of the solar system. This observation marks the first-ever detection of deuterium by any astronomical technique.

Jupiter - Observation of deuterated methane in the atmosphere.
During May 1971 a number of whole-planet spectra of Jupiter were obtained. Strongly evident in the spectrum of Jupiter are several J-manifolds in the P-branch of a band of CH3D. It is believed that this is the first observation of deuterium in any astronomical source. The spectrum of Jupiter is shown together with the spectrum of the sun, and a representation of a ratio of the spectrum of Jupiter to that of the sun.
Astronomical infrared spectroscopy with a Connes-type interferometer. III Alpha Orionis, 2600 to 3450 per cm.
Analysis of recent spectra of alpha Ori in the 3 to 4 micron region at a resolving power of about 10,000, showing clear evidence of the delta v = 1 sequence of the rotation-vibration bands of OH. A detailed investigation of the rotational and vibrational populations suggests that the OH is close to being in LTE at an apparent temperature of 4100 plus or minus 200 K. An OH abundance of 1.2 x 10 to the 20th molecules per cu cm and upper limits for H2O and H super 35 Cl of 8 x 10 to the 18th and 8 x 10 to the 17th molecules per cu cm, respectively, are deduced. It is also deduced that the rms turbulence velocity in the region of OH line formation is 11.5 plus or minus 2 km/sec. The implications of these data on abundances in M supergiant atmospheres are discussed.

Unique construction makes interferometer insensitive to mechanical stresses
Michelson-type interferometer with a cat-eye reflector operates effectively even in the presence of random mechanical stresses. A cubical beamsplitter with dichroic surfaces permits operation in infrared or visible light.
