deuterium enhancement in hot molecular cores is an important process, and we have estimated the d/h ratio by means of hdo and nh2d radio observations. the od radical, although predicted to be abundant by various chemical scenarios, has never been observed in space but would give important clues to d fractionation. we wish to detect and analyze three ir lines of od in our sample of hot cores. because these regions have temperatures above 100 k or more, they are capable of exciting the ir transitions of od. it will also be of considerable interest to determine the od abundance relative to oh as well as its excitation.

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.
