Abstract : Extended Huckel molecular orbital theory has been utilized to predict the relative stability of interhalogen and rare gas compounds. The calculations for the rare gas fluorides indicate that the relative stability goes, in order of decreasing stability, as XeF6, XeF4, XeF2, KrF2, KrF4, ArF2, KrF6, ArF4, ArF6, HeF2NeF4, and NeF6. Thus, the conclusions which are drawn are that argon difluoride may possibly be synthesized, but if made will be stable only at cryogenic temperatures. There appears to be no chance of making any of the fluorides of neon or helium difluoride. The preliminary results on the rare gas oxides show interesting trends but will require further analysis before definite conclusions can be drawn. The interhalogen calculations are not too encouraging but new methods which have recently been devised point the way to solutions of problems involved with calculations on interhalogen compounds. The dissociation rate of hydrogen fluoride in incident shock waves has been measured in various gaseous media. Work is progressing in the evaluation of all other rates involved in the formation of the experimental reaction profiles.
