✦ Synopsis


Variable temperature 'H NMR spectra of Se-methyl N.N-di-isopropyldiselenocarbamate, CH,SeC(Se)N(C,H,-i),, in CS, have indicated that internal rotations around both the carbamate C-N and isopropyl-nitrogen bonds are restricted below -40 "C; the compound exists as three rotational isomers with * Author to whom correspondence should be addressed.
