The trihalogens, I/sub 2/F and ClIF, and the pseudo-trihalogen, HIF, were observed as a result of crossed supersonic beams of pure HI or I/sub 2/ or ICl in argon carrier gas crossed with a hyperthermal beam of fluorine molecules in helium or helium--neon mixture. The I-F binding energies were determined to be 33, 31, and 26 kcal/mole for the I/sub 2/F, ClIF, and HIF molecules respectively. Mass spectrometric analysis indicated a preference for the geometry in which the least electronegative atom was in the central position. (DDA)
