✦ Synopsis

The hydntcd pos~on c& rexlIons wrth SCN-, OCN-, CN-, S'-, and SH-wcrc studrcd by mc.ms of the .mgular corrchtron tcchmque. The posllron forms bound stales with SCN-. CN-. and S'rcactron wlih SH-results in a pos&on bound state with S'-. but no1 with OCN-. App~~lly, lhc e& It was dlfficull to dctcrmmc the shapes of the bound-stdtc angular corrclalron curves. Only m the SCN-wsc could B very rough cstmdtc of the rate conskml be oblJmcd Estunaks of tic bindmg energies relnWc to those of Lhc corrcspondmg htidc Ion slalcs could bc dclcrmincd !-or SCN-.md S'-. mum (Ps), and ortho-Ps states. We added I .74 hl PPS (pyndmium-I-propane-3'.sulphonate) or 3 M NaNOx to the solutions to reduce the Ps components to 3.23%,
