relaxation times (1 Is) of cryptands [2.1.1], [2.2.1] and [2.2.2] as well as those of the corresponding crypeate complexes with Li+, Na+, and K+ in CDCl and CH OH:D 0 (9O:lO) were measured and the results are interpreted in terms of molesular co oreszion % and desolvation effects.
## Abstract The aromatic ^1^Hβ and ^13^CβNMR. spectra of some metal complexes of o, oβ²βdihydroxyazobenzenes are shown to be useful in distinguishing the two possible isomers (acolar and discolar) stemming from the non equivalence of the two ligating azo nitrogen atoms. The ortho aromatic carbon ato
## Abstract ^13^C NMR spectra for a number of furanoflavones are presented and analysed. The effects of various substituents are discussed.
