1. This work was supported by the National Research Council of Canada. High resolution n.m.r. spectra were obtained at the Canadian 220 MHz N.M.R. Centre, Sheridan Park, Ontario. We are indebted to Prof. M. Anteunis, State University of Gent, Belgium, for some 300 MHz spectra. This work is part of the Ph.D. thesis of A. O. Fulea

2. I.r. spectra of dilute (c < 0.003 M) solutions in CCl4exhibit the following normal “free” νOH (trace only), νQH…S intramol. (broad and intense), and δνOH values: (la) 3605, 3255, 350; (2a) 3607, 3266, 341 cm−1. At this low concentration intermolecular association can be excluded. In the u.v. the n ν* transition in n-hexane solution shifts from 389 nm inlato 401 nm inlc, and from 389 nm2ato 403 nm in2c
