this proposal is to use the short wavelength spectrometer to detect the forbidden pure rotational spectrum of the h3+ molecular ion in the ionosphere of jupiter. a detection of three or more lines, will: 1) be the first ever detection of this fundamental spectrum; 2) answer important questions about the concentration of h3+ in the jovian aurorae, and the physical conditions which prevail there. the h3+ ground state rotational spectrum covers the 10-40 micron region which is difficult to observe from the ground, but which is readily accessible to iso.s sws. proposed to use the sws in fabry-perot line scanning mode, to carry out the accurate measurements necessary to identify this spectrum. several lines are need to compute the r^ant temperature and column density.

Mission Description
The Infrared Space Observatory (ISO) was the worlds 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.
