Description we propose to use the lws in grating-only mode to measure the integrated intensities of the 112.1-um r(0) and 56.2-um (r1) rotational lines of hd in the atmospheres of uranus and neptune. the results will be complementary to the central programme observations of the same lines using the lws f-p. the determination of the deuterium abundances in the atmospheres of the giant planets is vital to our understanding of the composition of the primordial solar nebula and the early evolution of the planets. use of the iso lws to measure these hd lines allows the abundances to be derived in a very direct and model-independent way.

Mission Description The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
